How to measure your height without a ruler
To measure your height without a ruler, you can use other objects or techniques. You can stand next to a wall and mark the height of the top of your head on the wall, then use an alternate measuring device such as a book or a pen to measure the distance from the floor to the mark. You can also use your feet to measure room dimensions, or use your elbows to measure your height in relation to someone else’s. Additionally, you can use apps such as ARCore Ruler which takes advantage of augmented reality to measure your height.
