The mark directly in the middle of the inch denotes a measurment of 1/2' whilst the markings either side of it represent measurements of 1/4' and 3/4' respectively. Between those numbers are a series of shorter marks which represent fractions of an inch. These numbers sit next to long vertical marks which represent whole inches. When referring to the diagram above you'll see a series of large numbers marked 1, 2, 3, and 4. Most manufacturers have, therefore, opted to produce UK-spec tape measures with both metric and imperial graduations. Despite this almost all 21st Century technical, engineering or construction measurements are quoted in millimetres. We measure our height in feet and inches, our weight in stones and pounds and our speed in miles per hour.

Whilst Britain now officially operates a metric system of measurement, our nation still sees a curious mix of both metric and imperial measurements being used on a day to day basis. 41mm can also be referred to as 4.1cm (0.041m) but the majority of trades in the UK do tend to quote measurements in milimetres. The next small mark in line would be 42mm, the next would be 43mm and so on.

When looking at the image above, the 1st small mark after the 4cm point denotes a measurement of 41mm. Also, whilst a few tapes show '1m' to display the 1 metre mark, the majority will show '100cm'. Whilst the centimetres are clearly numbered, to make the blade easier to read the millimetres are not numbered. There are 10mm in each centimetre (shown by the ten spaces between each cm) and 100cm in each metre. In other words they're in centimetres and milimetres. The measurements towards the bottom of the image are metric. In response to our customers, therefore, we’ve put together this simple guide that explains just that!Ībove you'll see a picture of a metric/imperial pocket tape measure. We regularly get asked the question “how do you read a tape measure”. Whilst the seasoned professionals amongst you will no doubt be fully aware how to read the various markings on your tape, there will be amateurs, enthusiasts or those just starting off in their careers who aren’t yet so knowledgeable. The humble tape measure is the world’s most commonly used measuring tool, accompanying millions of tradesmen and contractors to work every single day. Got a tip to share? Then get in touch!
