Inner measure

Inner measure is a way of measuring inside a shape. We measure the inside of shapes to make sure that they have the right size and shape. To do this, we use a ruler or a measuring tape and compare how long or tall the shape is to a standard size that we decide on. For example, if you wanted to measure how tall a wall was, you could use a ruler or a tape measure to measure how far the wall was from the bottom to the top.
