What is the difference between a Class 1 and Class 2 tape measure?
As an example let’s compare a class I with a class II tape. EU guidelines state a class I tape up to 2m in length must be accurate to within a margin of 0.3mm. Under the same guidelines a class II tape of the same length should be accurate to within 0.7mm.
How accurate is a Class 2 tape measure?

What class is a Stanley tape measure?

What is a Class 2 tape measure?
As a rule most of the professional tape measures you will see on the market are Class II. These are adequate for the majority of users and a Class II tape allows for a potential error of ±2.3mm over a 10m length. For those after a higher level of accuracy you may want to consider a Class I tape.
What does the diamond on my tape measure mean?
The black diamonds which appear every 19 3/16” on metal tape measures are for spacing I-beam “timbers.” Several wood-product manufacturers offer I-beam “timbers” as a substitute for solid lumber floor joists. The diamond marks on tape rule blades are for spacing these engineered floor joists in new construction.
What is an EC Class 1?
Class 1 rated tapes are the most accurate and an error of no more than ±1.1mm over a 10m length can be anticipated, where a steel tape is used with a pulling force of 50N at 20°.

What is the 8 foot rule on a tape measure?
Use your tape measure as a slide rule.
Measure out 8 feet, 2 ¼ inches. Fold your tape measure so that it doubles back, and the metal hook lines up with 8 feet, 2 ¼ inches. Holding that in place, move the tape measure back up until you find 5 feet, 1 ⅛ inches and see where it intersects with the other side of the tape.
What is the toughest tape measure?
The BEST tape measure overall was the Stanley FATMAX. The FATMAX had the highest score in magnetic hold, debris testing, drop testing, hook durability and blade thickness.

Should a tape measure be calibrated?
Even if a tape measure is a Class I, and printed with the most accurate marks, it will still need to be calibrated sometimes. This is because of the second influence on accuracy — the end of the instrument. If the metal tip becomes bent or shifts out of place, it will affect the measurement.
Why are tape measures not accurate?
The habit of bending the tape measure into the corner and “eyeballing” the measurement can lead to inaccuracies. Instead, incorporate the width of the tape measure’s base into your measurement. Many tape measures have their base’s width printed on them, with three inches being the most common.
