If you’re wearing thick socks, remove those as well.

Do not stand on a carpet or a rug, which will sink a bit when you stand on it and may affect your measurement. Also avoid walls with molding or radiators along the bottom, which will make it impossible for you to stand fully flush against the wall.

If you are measuring alone, it may be easier to use an aerosol can such as a shaving cream can or air freshener. Press the bottom flat against the wall, which will ensure a right angle. [3] X Research source

Use a pencil so you can erase the mark from the wall when you’re done.

Repeat this process until you’ve reached the mark for your height. It may be easiest to keep track of each individual measurement on a separate sheet of paper so you can easily add them all together at the end. This is the simplest and most accurate way to measure your height without a measuring tape.

Other than an actual ruler, this will provide the most accurate measurement of your height. There are also ruler apps that you can download to your phone if you don’t have a printer accessible.

Continue until you’ve reached the mark you made recording your height. You may need to use the height of the bill—2. 61 inches (6. 6 cm)—to measure the final few inches of your height. You can also fold the dollar bill in half to measure approximately 3 inches (7. 6 cm), or in quarters for 1. 5 inches (3. 8 cm).

Make sure you’re using a standard sheet of printer paper. Other sizes of paper have different dimensions.

For example, with European shoe sizing, size 35 is roughly 9 inches (23 cm) and 40 is 10 inches (25 cm). You could also cut a piece of string the size of your foot, then use the string to measure the distance from floor to marking.
