5m tape measure buying guide

Updated: 22 October 2026

You are replacing a pocket tape, or buying a first 5 m one, and the listing is a pile of millimetres, classes, and standout claims. A 5m tape measure buying guide should settle the job before it settles the brand. Width decides whether the blade folds while you measure a room alone. The printed scale decides whether you read millimetres or inches. Class II is a legal allowance at stated conditions, not a sticker that makes a DIY tape legal for trade. Standout is the seller's claim, and the claims in this set do not agree. The [Tape measure 5m comparison](/hub/measuring-and-marking-tools/tape-measure-5m) holds the rows, with prices from about £2.38 to £21.50 on amazon.co.uk. This page does not rank them.

Blade width before brand

Start with how far the blade has to stay roughly straight. In this set, 19 mm is the pocket shelf: the Rolson 50535 is 19 mm at £2.38 and 181 g, and the Stanley Powerlock 0-33-553 is 19 mm at £9.51 and 209 g. The OX Trade twin pack is 25 mm, £9.00 for two, 520 g for the pair. The Stanley FatMax rows at 32 mm sit from £14.42 and weigh about 380–390 g. The Milwaukee listing states 30 mm. G4GADGET does not put a width in a specification field; the colour string includes 19 mm, which is not a width line. BuildWiz publishes a rule of thumb: about 1.5 m of standout on 19 mm, about 2.5 m on 25 mm, and about 3.3–4 m on 32 mm. That is a buying hint, not a measurement we made. A 19 mm tape is enough for a cupboard or a mark you can reach with the case in one hand. It is a poor bet when you hook the far skirting and read the near wall alone. Width does not tell you the scale. That split is on the metric-only or dual-scale page. If the blade has to stick to steel, the magnetic or plain hook page is the fork.

What Class II allows at 5 m

Class II is a number you can check, if the listing names the class. The Measuring Instruments Regulations 2016, Schedule 1I, set the Class II maximum permissible error at 0.3 + 0.2L millimetres, where L is the length in metres, rounded up. At 1 m that is 0.5 mm. At 5 m it is 1.3 mm. Those figures apply at 20 °C and a tension of 50 N, unless the tape is marked otherwise. Fifty newtons is about the weight of a 5 kg mass. It is a laboratory condition, not a kitchen-table test, and you should not hang a weight on a pocket blade to prove it. GOV.UK explains that these rules cover material measures of length put into use for trade. A printed Class II does not by itself make the tape legal for selling goods by length. In this set, Class 2 or Class II appears on the OX twin pack, the FatMax 0-33-719, and the FatMax 0-33-720. The magnetic FatMax FMHT0-33864 states ±0.5 mm to 1 m and does not state the allowance at 5 m. The FatMax Xtreme states ±1.6 mm over 5 m, which is not labelled Class I, II, or III. Rolson says High, Amazon Basics says MID, G4GADGET says standard measuring accuracy, and Milwaukee says 2. None of those is a class. One review of two Rolson tapes found about 1.8 mm of difference at 5 m. That is one pair, not a class test. Who each named tape is for sits on the best 5 m tape measure page.

Standout claims that do not match

Standout is how far the blade is claimed to stay roughly straight before it folds. It is not the length of the tape. A 5 m tape cannot stand out 11 m. The FatMax Xtreme listing still carries a bullet that says 11 metre maximum reach on a title that is 5 m/16 ft. Treat that bullet as a listing error. The FatMax 0-33-719 title says 3.3 m standout. The FatMax 0-33-720 bullets say the blade stays rigid up to 3.3 m, and the item highlight on the same listing says 4.2 m reach. G4GADGET's bullets say 2.8 m. The Milwaukee bullets say 4.5 m, and one review says the blade starts to bend around 240 cm and collapses around 350 cm. The OX pack, the Rolson, Amazon Basics, and the Powerlock do not state a standout. A 4.5 m claim on a 30 mm blade is more than the rule of thumb. Choose the width for the job, then read the standout as a claim you can test on the first long pull. Creasing is how a tape stops being the length it was.

Lock, case, and weight

The lock is how you keep a reading while you mark, and how the blade comes home. Amazon Basics describes a self-lock that holds as the blade extends, with a button to retract, and reviews say that return is quick. The Rolson is an auto lock. G4GADGET's bullets describe two hold buttons and a top slider. The OX bullets name a thumb lock. FatMax 0-33-719 is a positive lock that some reviews call stiff. A self-lock is convenient with one hand, and it whips if you press the button while the blade is still out. Case words slip. The Powerlock case field says plastic and the bullets say chrome; reviews say the chrome look is plastic. Weight is the belt question. Light tapes in this file are about 150–209 g. A single 32 mm FatMax is about 380–450 g, and the Milwaukee is 410 g. The OX twin pack is 520 g because it is two tapes. A clip does not replace a wide blade. One row, B0009VX200, has no price, weight, or title, so it cannot sit on a shelf. An 8 m tape is a different length. This category stops at 5 m.

Common questions

Is 19 mm enough for a 5 m tape?
It is enough when the measurement is within arm's reach or when someone else holds the hook. The 19 mm tapes in this comparison are the Rolson at £2.38 and the Powerlock at £9.51. BuildWiz's rule of thumb puts standout for that width at about 1.5 m, and neither listing states its own standout. For a room you measure alone, look at 25 mm or 32 mm instead, and expect the extra weight.
What does Class II mean in millimetres at 5 m?
Under Schedule 1I, Class II is 0.3 + 0.2L millimetres. At 1 m that is 0.5 mm. At 5 m that is 1.3 mm, at 20 °C and 50 N, unless the tape is marked otherwise. Do not pull the blade with a 5 kg load at home to check it. A listing that only says High, MID, or the digit 2 has not stated this allowance.
Why do standout figures disagree?
Sellers use standout and reach for different distances, and some pages copy a figure from another length in the same family. In this set you will see 2.8 m, 3.3 m, 4.2 m, 4.5 m, and an impossible 11 m bullet on a 5 m Xtreme. A review can also describe the blade folding short of the claim, as one Milwaukee review does around 350 cm. Use the number as a claim, then try one careful pull.
Do I need a belt clip and a wrist strap, or a wide blade?
You need the wide blade if the job is a long unsupported pull. You need the clip or the strap if the tape has to stay on you between marks. Several cheap tapes include a strap and still use a 19 mm blade. A 32 mm FatMax at about 390 g is the opposite trade: reach first, pocket second. Buy the feature that matches the measurement you keep getting wrong.
Is a printed class the same as legal for trade?
No. GOV.UK ties the Measuring Instruments Regulations to measures put into use for trade. Class II on a DIY listing is the claimed accuracy allowance, not a licence to sell fabric, rope, or timber by length. If you do sell by measure, you need the rules that apply to that use, not a bullet on amazon.co.uk.
Should I buy 8 m instead?
Only if the runs you measure are longer than 5 m. This comparison is 5 m tapes. An 8 m tape is heavier and is a different category. A 5 m blade already includes the 3 m and 4 m marks you use indoors. Buying 8 m does not fix a kink, a missing class, or a scale you cannot read.
What weight am I putting on a belt?
Pocket tapes here are about 150–209 g. A single 32 mm FatMax is about 380–450 g, and the Milwaukee is 410 g. The OX twin pack is 520 g for two tapes, so one of them on the belt is half of that only if they weigh the same, which the listing does not split out. If your belt already carries a drill, a 390 g tape is the one you notice.
