Contour gauge buying guide

Updated: 22 October 2026

You are looking at a row of orange plastic gauges on amazon.co.uk and trying to decide which one will copy a door lining or a heating pipe. A contour gauge buying guide only helps if it puts the features in the order that changes the line on the board: width, then depth, then a lock you can trust, then pin thickness, then tension. Stars and a low shelf price come after that. The [contour gauge comparison](/hub/measuring-and-marking-tools/contour-gauge) holds the prices, review counts and the row for each ASIN captured on 19 October 2026. Nothing here is a lab test. If you buy through our links, a qualifying purchase can earn us a commission at no extra cost to you.

Width and depth first

Measure the obstacle before you compare brands. A 6 inch body, the SULIVES listing at £8.09, covers a small pipe and little else. UK reviewers of that ASIN said they wanted a longer gauge. A 10 inch or 250 mm body is the usual size in this set for a door jamb. MECHEER states 25 cm. Depth is a separate number. MECHEER's bullets state a maximum of 6 cm. DODOWIN's 10 inch bullets state about 10 cm. wolfcraft's English page states 30 mm depth. Screwfix lists the Tracer ACG2, the same model code as ASIN B0CC31VN8M, with a stated 70 mm scribe depth. If your architrave stands proud by 80 mm, a gauge whose bullets stop at 6 cm cannot reach the back of it. If no depth is printed, as on the single JOREST, check the moulding with a ruler.

A lock is not the same as a tension screw

Once the pins can reach the shape, the next question is whether that shape has to travel. A lock clamps the pins so you can walk the gauge to the bench. Friction only holds them while nothing nudges the row. Amazon Basics is the only title in this set that says non-locking friction-fit in plain words. A tension screw changes how stiff the pins are, and it is not proof that a clamp exists. The single JOREST says tightness is set in manufacture. MECHEER's bullets say not to pull the lock to the end of its travel. A clamp you wind home until it stops can be the way that lock fails. If you will trace at the obstacle, read contour gauge with lock before you pay extra for a lever you will never close.

Pin thickness decides the fine work

Plastic blades in this set are coarse compared with a needle gauge. JOREST states 0.05 inch blades on the single 10 inch and the connectable pair. MECHEER states 0.2 cm, and UK reviews call those pins too thick for a fine profile. Axminster's listing for a Shinwa 150 mm profile gauge states 0.8 mm needles. That needle tool is not in this comparison.

What the star rating will not tell you

SULIVES shows the sharpest mismatch. The bullets say a robust metal lock. United Kingdom reviews of the 6 inch ASIN say the tool they received had no lock, and one says a securing screw snapped after two uses. A 3.6 from 67 reviews is the weakest star line here, at £8.09. Tracer's amazon.co.uk line is 4.6 from 32 reviews. One of six UK review texts says the bars still move when the lock is on. A high star line on a thin sample does not settle that. Use the best contour gauge UK page when you want a named pick and a reason to skip it.

Common questions

Should I buy a 5 inch or a 10 inch contour gauge?
Buy the width that covers the obstacle in one press. A 5 inch or 6 inch body suits a single pipe. A door lining and most flooring planks in this set are copied with a 10 inch or 250 mm body. The 6 inch SULIVES listing drew reviews that asked for a longer gauge, so do not assume a short body will do a lining.
Do I need a lock?
You need a lock if the outline has to survive the walk to the saw. If you will pencil the board while the gauge is still against the obstacle, a friction fit can hold, which is what Amazon Basics states. A lock printed in the bullets and missing from the tool, as UK reviews report for SULIVES, is a return rather than a bargain.
How deep do the pins need to go?
Deep enough to pass the proudest part of the moulding. Use the figure printed for that product, then measure your architrave. If the proud face is deeper than the pins, the copy stops at the front bead. A listing with no depth stated has not answered the question.
Are thicker plastic blades less accurate?
On a fine bead, yes. A 0.2 cm pin, which MECHEER states, cannot follow a step narrower than the blade. JOREST's stated 0.05 inch is thinner and still coarse next to a 0.8 mm steel needle, the figure Axminster prints for the Shinwa 150 mm.
Is a stainless needle gauge a different product?
Yes. The gauges in this amazon.co.uk set are plastic or ABS blades. A needle gauge, such as the Shinwa sold by Axminster with 0.8 mm needles, is a different tool for finer profiles. Do not expect an ABS blade of 0.05 inch or 0.2 cm to match that. If the beads matter, leave this set.
What if the listing says metal lock and the reviews say there is none?
Believe the conflict, not the bullet, until you see the tool. That is the SULIVES 6 inch case: the bullets say a metal lock and UK reviews say there is no lock. Open the parcel and look for the clamp before you cut a board. If it is missing, the listing and the tool disagree, and the consumer-rights route is a return rather than a workaround.
