You’ll need a tape measure, and something to mark the dimensions with. Start by measuring the length of the item, from top to bottom. Then, measure the width of the item, from side to side. Finally, measure the depth of the item, from front to back. Once you have all three measurements, add them together to get the total size of the item.
