Let’s have a quick look at one of the most basic skills if you want to work with wood or make just about anything – how to use a tape measure properly! I’m forever seeing people using this simple tool wrongly and in this video I want to address the most common mistake I see – the difference between taking inside and outside measurements.

How to use a tape measure?
Let’s say you want to measure 500mm from the end of a piece of wood. Simple, hook the tab over the end of the piece, pull the tape measure back and make your mark at 500mm – simple!
OK, so now let’s imagine there’s a wall at the end of this piece of wood so you can’t hook the tab over the edge. Fine you say, just hold the tab on the end and take a measurement as normal. BUT if you’re now pulling the tape measure back from the tab you’re holding there’s a reasonable chance you’re doing it wrong and you’ll have an inaccurate measurement.
Simple Rules For Using a Tape Measure
If you’re taking an OUTSIDE measurement, in other words one where you can hook the tape measure end over something, then PULL the tape back towards you from the hooked tab.
If you’re taking an INSIDE measurement, in other words one where you can’t hook the end over something, then you need to pull the tape out to the desired length and then PUSH the whole thing towards the tabbed end. This will automatically adjust for the thickness of the hooked tab that you’re no longer using and you’ll have an accurate measurement.
- OUTSIDE MEASUREMENT: PULL
- INSIDE MEASUREMENT: PUSH
Test it for yourself next time you measure something! If you still get two different readings it’s time to buy a new tape measure!
Metric-Only Double Sided Tape Measures
My favourite tape measure by a country mile is the Advent Vice-Versa Metric-Only double sided measuring tape.
This has a few major advantages:
- It’s double sided
- It’s metric only
- It can be used left or right handed
- The end hook can be used either way around
