The best Angle finders, compared.
Top pick: YUNSHU digital angle rule, 200 mm Best value: Trend DAR/200 digital angle rule – Score 74 at £18.49, 4.5 from 5,914, a hinged stainless rule a pound and a half under the two higher scores. Updated October 2026.
An angle finder on amazon.co.uk is a hinged digital rule for a corner, a magnetic box that reads tilt after you zero it, or a mechanical mitre protractor with no battery. You use one for skirting and trim in a house that is not square, or to set a mitre saw, table saw or bandsaw blade. How the type fits a job is in the [angle finder buying guide](/hub/measuring-and-marking-tools/angle-finder/sub/angle-finder-buying-guide). A hinged digital rule opens into a corner, which is the shape for skirting and trim. A magnetic box, including a laser box, is zeroed on the table and then reads a blade or a fence. Some of its about-this-item bullets describe a tape and contradict the title. A contour gauge, a sliding bevel or a spirit level is a different category. You match the type to the job before you compare the printed resolution. A mechanical protractor is for a saw setting that still works when a coin cell is flat. About 200 mm closed is the common arm length. If the bullet and the material field disagree, both stay on the page.

Personal buying guide
Question 1 of 2
What are you measuring?
YUNSHU, at £9.49, is a hinged digital rule that prints ±0.5° and a 0.05° step over a full circle, with arms of 200 mm folded and 400 mm open, at 110 g. The bullets also name a zero, a hold, a lock, and a reversible display, which is the control set a corner transfer needs. The listing is five stars from only four reviews, and the saved listing holds two UK texts, one a detailed praise of the screen and one an emoji. That star line is not a sample you can weigh against a listing with thousands of reviews. The specification line says one CR2032 is included, while the bullets say two, so the box contents are not settled on the page. Carbon fibre is claimed in the bullets and is not described in a review. You still need to seat it on a known square before you trust the printed error band.
Pros
Cons
Best for: You want a cheap hinged rule with a printed ±0.5° and you will check a square yourself.
Less suitable: You want a large UK review sample before you trust the accuracy line.
Specifications
Common questions
What accuracy is printed?
The bullets say ±0.5° and 0.05° resolution, over 0–360°, inside and outside.
How many batteries are included?
The specification line says 1 CR2032 included. The bullets say 2 batteries included.
How many reviews describe it?
The listing says 5.0 from 4. The saved listing has two UK texts, one of them a detailed praise of the screen and one an emoji.
LEXIVON LX-230, at £19.99, is a 7 inch mechanical mitre protractor at 231 g, with an aluminium handle and an alloy-steel blade field, and it needs no coin cell. The amazon.co.uk line is 4.8 from 8,787 reviews, the largest count in this set, which is why the score of 78 is the highest here. UK reviews describe inside angles, two scales, and skirting work, and one reviewer says the scales are hard to read at first and still prefers that to a flat battery. Another says one scale is the mitre and one is a single cut. Five about-this-item bullets describe a tape measure with stud centres, and those bullets contradict the title and the reviews, so they are not treated as specifications. No degree accuracy is printed. If you want a digital number without learning a scale, this is the wrong row.
Pros
Cons
Best for: You want a saw protractor that still works when a battery is flat.
Less suitable: You want a digital number without learning a scale.
Specifications
Common questions
Is this a tape measure?
The about-this-item bullets describe a nylon blade and stud centres. The title, item type Protractors, included line Miter Saw Protractor, and the UK reviews describe an angle finder. The tape bullets are not treated as specs.
What do you have to learn?
Kiwisailor says the scales are hard to read at first, and prefers that to a flat battery. David Bond says one scale is the mitre and one is a single cut.
Does it need a battery?
The power field says hand powered. Reviews treat the lack of a battery as the point.
Trend DLB, at £19.95, is a 28 mm ABS magnetic box at 170 g, and the listing is 4.7 from 5,486 reviews, ranked first in inclinometers on this file. You zero it on the saw table and then read the blade, which is how UK reviews describe mitre saws and table saws. The saved saved listing does not print a plus-or-minus accuracy or a resolution. A later manufacturer how-to states ±0.2°, and that figure is not treated as a fact of this saved listing. One reviewer notes that it measures in one direction at a time, and it has no hinged arms, so a corner between two walls is outside the tool. Another asks why the magnets are not on all sides, and one calls it pricey next to cheaper boxes. The listing states a one-year manufacturer warranty, and battery chemistry is not on the spec block.
Pros
Cons
Best for: You want a small magnetic box to zero a saw table and read the blade.
Less suitable: You need the angle between two walls.
Specifications
Common questions
Can it set a mitre-saw bevel?
The bullets say zero it on the saw table, then use the magnetic base on the blade. UK reviews describe mitre saws and table saws.
Can it measure a skirting corner?
It has no hinged arms. Ian notes it measures in one direction at a time. A corner between two walls is the job of a hinged rule.
What is the complaint in the reviews?
Piku calls it pricey. Mr Stewart D Wilson asks why the magnets are not on all sides. A repeated hardware failure is not in the 50 texts.
Trend DAR/200, at £18.49, is a stainless hinged rule at 163 g with 0.1° steps, a centre locking knob, a zero, and a CR2032, in the 200 mm style with a dimensions line of 40 by 3.5 cm. The amazon.co.uk file does not print an accuracy in degrees, while Trend’s own UK page states 0.3° accuracy, which is a different document from this listing. The star line is 4.5 from 5,914 reviews, and in 50 UK texts the lock and the reading are the usual praise. One reviewer says the plastic battery cover is fiddly and broke, which is the repeated snag rather than a degree-scale failure, and the warranty field on the page says no warranty. This is the hinged rule in the set with a large review count for skirtings and for carrying an angle to a saw. It will not stick to a blade.
Pros
Cons
Best for: You want a hinged stainless rule with a large review count for skirtings and saw transfer.
Less suitable: You want a magnet on a saw blade. That is the Trend box, not this rule.
Specifications
Common questions
Does it measure inside corners?
The title says internal and external measurements. The bullets name skirtings, cornices, shelves, and a lock for transfer to a table saw or mitre saw.
What fails in the reviews?
Across 50 UK texts, accuracy and the lock are the usual praise. Amazon Customer says the plastic battery cover is fiddly and broke. One 2015 text describes a 500 mm rule and is not used as a spec for this 200 mm model.
Is a degree of accuracy printed on amazon?
This saved listing prints 0.1° increments and does not print an accuracy such as 0.3°. The warranty line says no warranty, spelled as on the page.
AivaToba LJC-44, at £15.99, prints ±0.1° and a 0.05° step on a hinged rule of 200 mm folded and 400 mm open, at 110 g. The bullets say carbon fibre and ABS, while the material field says Metal, so the page does not agree with itself about what you are holding. Hold, invert, and zero are in the bullets, and the shared texts do mention skirting and stair use. The 4.4 from 3,699 reviews, the best-sellers line, and the 50 saved UK texts are the same block as the grey AivaToba at £16.99. Adding the two counts would count one sample twice. Inside that block, reviewers describe about half a degree out at a right angle, which is wider than the ±0.1° printed on this ASIN. The included-components field says no, and the battery is not on the spec line.
Pros
Cons
Best for: You want the cheaper of the two AivaToba listings and you treat the shared reviews as one sample.
Less suitable: You need a review sample that is clearly about this model, or a material claim that matches the field.
Specifications
Common questions
What is it made of, on this listing?
The bullets say carbon fibre and ABS. The material field says Metal. The weight is 110 g. The other AivaToba file weighs 230 g and says stainless.
Are these reviews only for LJC-44?
The 50 UK texts, the 4.4 from 3,699, and the best-sellers line are the same as ASIN B089W9Q9KC. Treat them as one shared block, not two samples.
What accuracy do the texts report?
mark shorrocks says about half a degree. Thomas Corcoran says about 0.5° out at 90° against squares. The bullet on this ASIN says ±0.1°.
The grey AivaToba, model AivaToba-123, is £16.99 and prints ±0.3°, with stainless steel in the bullets, Metal in the material field, and a weight of 230 g. The listing warns that the edge is sharp. It is the heavier of the two AivaToba rows, and the shared texts include skirting and spindle jobs as well as the faults. The 4.4 from 3,699 and the 50 UK texts are the same block as LJC-44, so this is not a second independent sample. Reviewers in that block report random readings, about half a degree out at a right angle, tiny instructions, and unclear battery orientation. Three button cells appear in one review text, not on the specification block. You pay a pound more than LJC-44 for the stainless claim and the extra mass, and you still cannot add the review counts together.
Pros
Cons
Best for: You want the stainless-claimed AivaToba and you will not add its review count to LJC-44.
Less suitable: You want instructions that explain the battery, or an independent review sample.
Specifications
Common questions
What is it made of, on this listing?
The bullets say stainless steel with a sharp edge. The material field says Metal. The weight is 230 g.
How does this differ from AivaToba LJC-44?
This file is £16.99, grey, ±0.3°, 230 g, model AivaToba-123. LJC-44 is £15.99, black, ±0.1°, 110 g, carbon fibre in its bullets. The saved UK reviews match.
What goes wrong in the texts?
Steve B reports random readings. Thomas Corcoran reports about 0.5° out at 90°. Tony Purkis and POW say the instructions are tiny or missing and the battery orientation is unclear.
Entatial, at £32.50, is the longest hinged rule in this set, a 500 mm stainless rule at 420 g with metric and imperial scales claimed. The bullets state 0–360° and 0–500 mm, and they do not print an accuracy or a resolution. The listing is 4.3 from 7 reviews. Two of three UK texts say a CR2032 was not in the box, and one says the dial does not hold well if you want to trace the angle onto wood. That is a thin file for the highest price here, and the score stays at 54 because seven reviews only add the small volume band. The extra length is real if you specifically need a 500 mm arm. It does not come with a stated accuracy or with a lock that the saved texts say holds.
Pros
Cons
Best for: You specifically want a 500 mm stainless digital rule and you will buy a CR2032.
Less suitable: You want a stated accuracy or a lock that reviewers say holds.
Specifications
Common questions
Is a battery included?
The specification block does not say. John and david, two of three UK reviews, say a CR2032 was not in the box.
Does the angle stay locked?
John says the dial does not hold well if you want to trace the angle onto wood.
What accuracy is printed?
None. The bullets state 0–360° and 0–500 mm, stainless steel, and metric and imperial scales.
Flintronic, at £9.99, is an ABS hinged rule at 100 g that prints ±0.5° and a 0.05° step, and it carries the largest review count under £11 in this set at 4.2 from 333. Some UK texts do describe a usable stair and a bay window, so the file is not only complaints. In the 29 UK texts, reviewers report 175° on a flat open, 87° on a set square after zeroing, a display past 400° with failed LED segments, and random numbers that need a reset. Those reports are why the score carries an eight-point penalty. The title says 200 mm, while the bullets say 21.9 cm folded and 40 cm full length. Hold and zero are named, and a separate arm lock is not. If a known square is still several degrees out after a fresh zero, reject the tool rather than subtracting the error in your head.
Pros
Cons
Best for: You will zero it and reject it if a known square is still degrees out.
Less suitable: You need the first reading to match a set square.
Specifications
Common questions
What accuracy is printed?
±0.5°, resolution 0.05°, range 0–360°. The bullets say to zero on the flat before each measurement.
Do the reviews match ±0.5°?
Some do. James says a flat open reads 175° and a set square reads 87° after zeroing. Justin Reeves says it reads over 400° and LED segments fail. Josh Taylor says random numbers need a reset.
How long is it?
The title says 7 inch / 200 mm. The bullets say folded 21.9 cm and a full length of 40 cm.
Pnoyws, at £9.79, is another hinged rule in the £10 band, with yunwailc as the manufacturer and Pnoyws as the brand, and it prints ±0.5° and a 0.05° step on arms of 200 mm folded and 400 mm extended, at 100 g. The bullets name a zero, a hold, a lock, and a CR2032, and origin is listed as China. The amazon.co.uk line is 4.1 from 17 reviews, which sits under the 20-review step used in the score. Three UK texts are saved, all short praise, and none of them describes a fault or checks the carbon-fibre claim. The page asks whether the rule is metal, while the bullets say carbon fibre at the stated 100 g. A small praise file is not the same as a large one that has had time to include failures.
Pros
Cons
Best for: You want another £10 hinged rule with a printed ±0.5° and a small review file.
Less suitable: You want the material confirmed by reviewers, or a large sample.
Specifications
Common questions
Is it metal?
The page asks that. The bullets say carbon fibre. The weight is 100 g.
What accuracy is printed?
±0.5° and 0.05° resolution, 0–360°, 200 mm folded and 400 mm extended.
What do the reviews say?
Three UK texts are in the file, all short praise. The listing count is 17. None of the three describes a fault.
ZITUZY, at £8.99, is the cheapest magnetic laser box in this set, listed at 160 g with USB charging and no loose coin cell, and it is meant to read tilt on metal rather than open into a skirting corner. The bullets do not describe hinged arms, so a wall-to-wall angle is outside this shape, and no accuracy figure or resolution is printed. The amazon.co.uk line is 4.0 from 9 reviews. Of the three UK texts in the file, two are short praise, and Richard R. says the instructions are not in English. A case is asked about on the page and is not in the included line. Treat the first use as a check on a known square, and reject the unit if that square is still degrees out.
Pros
Cons
Best for: You want the cheapest magnetic box in this set and you can check it on a known square.
Less suitable: You need a printed accuracy, or arms that sit in a skirting corner.
Specifications
Common questions
Does the listing state an accuracy?
No. The bullets say clear, accurate readings and do not print a ± figure or a resolution.
Is there a carry case?
The page asks the question. The included-components line lists only the magnetic instrument.
Are the instructions in English?
Richard R., one of three UK reviews in the file, says there are no English instructions.
Qivine, at £10.89 and 150 g, is a magnetic laser box that claims ±0.2°, four magnetic sides, a dual laser, and USB-C charging, so there is no loose coin cell. It reads tilt, including a four-times-90° mode, and the bullets do not describe two arms for a skirting corner. The listing is 3.6 from 44 reviews, the lowest star line in this set, and the score takes a ten-point penalty for the fault texts. Of 25 UK texts, reviewers describe a unit that would not power on, a laser about 5 mm out, magnets that slip, and instructions that do not match the buttons. Laser class is not printed. A rechargeable box can still be the wrong buy if you need it square on the day it arrives.
Pros
Cons
Best for: You want a rechargeable magnetic box and you will calibrate it before you trust the laser.
Less suitable: You need a corner reading for skirting, or a tool that is square on arrival.
Specifications
Common questions
Does it measure a skirting corner?
The bullets describe a four-sided magnetic box for blades and metal. They do not describe two arms that sit on two walls.
What do reviewers say about the laser?
ian T says the laser is weak outside. Nathan Talbot says about 5 mm of run-out up or down, and that the body needed squaring. Mr. S. Derry likes the line but not the accuracy.
Does it work out of the box?
DAVE GLASS says the first unit did not power on and the charge-port seal was fitted wrongly. Matthew Davsion and Fizeroo say it needs calibration against a known level, and that the printed instructions were wrong.
Shelf prices, stars and review counts are the amazon.co.uk listings saved on 19 October 2026. No angle was cut in a lab, and the score does not rank the printed accuracy. The saved formula is score = round(amazon rating / 5 × 60) + a volume band, then a stated penalty where the saved UK texts contradict the accuracy line. Volume band: 5,000 or more reviews +20, 1,000 or more +16, 200 or more +12, 20 or more +6, otherwise +2. Flintronic loses 8 because texts report 175° on a flat open and 87° on a set square. Qivine loses 10 because texts describe a unit that would not power on, a laser about 5 mm out, and magnets that slip. Each AivaToba row loses 8 because the shared texts include random readings and about half a degree out at 90°. The two AivaToba counts are the same 3,699 and are not added. The highest score is the top pick, once: LEXIVON LX-230 at 78. Best value is Trend DAR/200 at 74 and £18.49, a pound and a half under the two higher scores, with a large independent sample. Trend DLB scores 76 and stays unbadged because it is a magnetic box for a blade, a different job. The weights below are the two additive parts of that formula, scaled so they sum to 100. The penalty is a subtraction, not a third award.
Amazon star line
75%The star part is round(amazon.co.uk rating / 5 × 60). That is three quarters of the 80-point ceiling before any penalty, so the weight here is 75. A 4.8 line is 58 points in the formula. A 4.0 line is 48. This is not a workshop measurement of degrees.
Review volume
25%The volume band adds 20, 16, 12, 6 or 2 points. That is the other quarter of the ceiling before any penalty, so the weight here is 25. LEXIVON, Trend DAR/200 and Trend DLB are in the 5,000-review band. A listing with fewer than 20 reviews stays on +2. A small five-star file is not treated as a large sample.
You are choosing a tool for a corner that is not square, or for a blade angle on a saw, not a spirit level and not a contour gauge. These eleven amazon.co.uk listings are the rows on this page. Prices run from £8.99 to £32.50 on 19 October 2026. The score uses the star line and the review count, then a penalty where UK texts contradict the accuracy line. It is not a workshop test of degrees.
An angle finder on amazon.co.uk is one of three tools. A hinged digital rule opens into a corner, which is the shape for skirting and trim. A magnetic box, including a laser box, is zeroed on the table and then reads a blade or a fence. It cannot span a skirting corner. A mechanical mitre protractor has no battery. The LEXIVON LX-230 is that type. Some of its about-this-item bullets describe a tape and contradict the title. Do not treat it as a tape.
Houses are often not square. A 45° mitre is the right cut only when the corner is 90°. Measure the corner, then prove the setting on offcuts. A rule of thumb only: 0.5° on a 100 mm width is about 0.9 mm of gap.
Halving the screen without knowing whether it is the wall angle or the saw angle is a common miss. A 91° external example that then says set the saw to 22.5° disagrees with the 44.5° step in the same example. Do not copy 22.5° for that reading.
Resolution is the step, 0.1° or 0.05°. Accuracy is the error band the seller prints. A 0.05° step with a ±0.5° claim is not finer than a 0.1° step with a ±0.3° claim. Listings from £8.99 to £10.89 include texts of degree-scale errors.
A magnetic box reads tilt on one surface. It cannot span a skirting corner. On a hinged rule, zero on the flat before the measurement. If a known square is still several degrees out, reject the tool.
Type matches the job. Hinged arms open into a corner: Trend DAR/200, YUNSHU, both AivaToba ASINs, Pnoyws, Entatial and Flintronic. A magnetic box is zeroed on the table and then reads the blade. Trend DLB is that box. Qivine and ZITUZY are magnetic laser boxes. None of those three can span a skirting corner. A mechanical protractor is the choice when you want a saw setting and no coin cell. LEXIVON LX-230 is that row.
Stated accuracy comes before resolution. Resolution is the step, 0.1° or 0.05°. Accuracy is the error band the seller prints, from ±0.1° to ±0.5°, or 0.3° on Trend’s UK page for the DAR/200. A 0.05° step with a ±0.5° claim is not finer than a 0.1° step with a ±0.3° claim. The amazon file for the DAR/200 prints 0.1° increments and does not print 0.3°. Do not state Trend DLB as ±0.2° from this file. ZITUZY and Entatial print no accuracy figure. Check a known square after zeroing.
Three typical situations, each with a recommendation from this comparison.
You need arms that sit in a corner that is not 90°, then a lock that holds on the way to the saw. The Trend DAR/200 is best value at £18.49, a stainless 200 mm rule with 4.5 from 5,914 reviews. The amazon file prints 0.1° steps and does not print an accuracy in degrees. It will not stick to a blade.
You zero a magnetic box on the saw table and then read the blade. The Trend DLB is £19.95, 28 mm, with 4.7 from 5,486 reviews and a score of 76. It has no hinged arms, so a corner between two walls is outside the tool. The saved file does not print a plus-or-minus accuracy.
You want a mitre protractor that still works when a coin cell is flat. The LEXIVON LX-230 is the top pick at £19.99, 4.8 from 8,787 reviews, score 78. UK reviews describe two scales. Five about-this-item bullets describe a tape and are not treated as specifications. No degree accuracy is printed.
The top pick is the LEXIVON LX-230 at £19.99. It has the highest score in this set, 78, from 4.8 stars and 8,787 reviews. It is a mechanical protractor, not a claim that it is the most accurate finder in degrees, and it still works with a flat battery. Best value is the Trend DAR/200 at £18.49, score 74, 4.5 from 5,914, a hinged stainless rule for a skirting corner and a pound and a half under the two higher scores. Trend DLB scores 76 and is a magnetic box for a blade, close in price, and a different job. Neither badge means the most accurate angle finder in the UK. Listings from £8.99 to £10.89 include texts of degree-scale errors, weak magnets, or random readings.
