Folding rule buying guide

Updated: 22 October 2026

You are about to buy a rigid metre stick on amazon.co.uk, and the cheapest plastic rule is one click away. A folding rule buying guide starts with the job, because a 1 m stick that bends will not draw the line, and a 2 m rule with no class mark will not support a tolerance you meant to quote. This page orders the choice. It does not name a single winner. The six listings are on the [measuring stick comparison](/hub/measuring-and-marking-tools/measuring-stick). We read the amazon.co.uk listings and UK review texts saved on 21 October 2026, plus Schedule 1I. This is not a lab test. A qualifying purchase can earn us a commission at no extra cost to you.

What the stick has to do

A folding rule is hinged links you open into a straight edge, usually about 1 m or 2 m. You want it when a tape sags. You do not want it for a room length or a ceiling height. Firecore is an aluminium telescopic staff listed as 3 m, and it does not fold into a straightedge. If the next mark is a floor or a ceiling, read the telescopic levelling staff page. None of the six listings states a sliding brass end. Home marking is not automatically trade use. If you are selling by length, an unmarked rule is the wrong evidence.

1 m or 2 m

Length is the first reject. The only 1 m rule is the Amtech P5185 at £4.38, red plastic in four sections, with metric and imperial marks. Amazon.co.uk shows 4.0 from 642 reviews. UK texts like it for a rough length, and they say the plastic is soft and will not sit flat. It cannot span a 1.8 m board without a second bite. The other four folding rules are 2 m sticks: SOL at £4.99, wolfcraft at £5.89, QWORK at £5.99, and Presch at £9.99. QWORK's title says 6 ft 6 in and the item-length field says 198.1 cm, so keep both figures. Buy 1 m only when every mark sits inside that metre and you accept the bend. Buy 2 m when the board or the pair of marks is longer.

Class III, and a rule with no class

Only Presch states Class III. Under Schedule 1I the class III error is 0.6 mm plus 0.4 mm per metre, which is 1.4 mm at 2 m, plus up to 0.5 mm from the joints, at 20 °C. That sentence applies because the listing states the class. It does not apply to wolfcraft, SOL, QWORK, or Amtech. An unmarked £5 rule is not class III by being wood or by a high star average. You need the stated class to quote a tolerance. You do not need it when the pencil line itself is thicker than 1.4 mm. A stated-class plastic rule such as Stanley 0-35-229 sits outside these six ASINs.

Inches, wood, and an angle scale

Amtech states metric and imperial marks. QWORK's bullets state 1/16 inch graduations and a metric scale, and more than one of the 38 UK texts says a section broke within days or weeks. wolfcraft's field is 2,000 mm and does not state inches, which is what some UK buyers had expected. SOL and Presch do not state an imperial scale. UK reviews say this plastic is soft, so a general wet-site tip for plastic does not make the Amtech the damp-site rule. wolfcraft names beech and the Czech Republic. QWORK names birch and China. Only Presch states an angle scale. Open every joint and check that the units match the listing.

Common questions

Should I buy a 1 m or a 2 m folding rule?
Buy 1 m only when the marks stay inside that length. In this set that is the Amtech P5185 at £4.38, and UK reviews say the plastic bends. Buy 2 m when the board or the pair of marks is longer. SOL, wolfcraft, QWORK, and Presch are the 2 m rows, from £4.99 to £9.99 on this capture. A second bite with a short rule is where a short error becomes a cut error.
What does class III mean in millimetres?
For a rule that states class III, Schedule 1I gives 0.6 mm plus 0.4 mm per metre, so 1.4 mm at 2 m, before up to 0.5 mm from the joints, at 20 °C. Only Presch states that class in this set. The figure is a legal maximum for that claim. It is not a measurement Products Compared made on the stick.
Is an unmarked £5 rule class III?
No. wolfcraft at £5.89, QWORK at £5.99, SOL at £4.99, and Amtech at £4.38 do not state a class. Wood, a European origin line, or a high star count does not fill that blank. If you need the formula, you need the stated class, which here means Presch.
Wood or plastic if the site is damp?
A general workshop guide prefers plastic in the wet and wood in the dry. The only plastic rule in this set is the Amtech, and UK reviews say it bends and will not lie flat. That review limit beats the general material tip. A glass-filled class III plastic rule exists in the UK trade and is not one of these ASINs.
Which listing actually has inches?
Amtech states metric and imperial marks on a 1 m plastic rule. QWORK states 1/16 inch graduations and metric marks, with a title of 6 ft 6 in and an item length of 198.1 cm. wolfcraft, SOL, and Presch do not state an imperial scale. QWORK's graduation field 0.06 Hundredths-Inches is not a tolerance.
Is the angle scale on every rule?
No. Only Presch states an angle scale, at £9.99, alongside Class III. The other folding rules do not name one. A question on the Presch listing asks about a locking mechanism, and the spec does not name a lock as a separate part.
