The Lab Cleaning Brush

Place the bag on the flat surface with the outside facing up.
Measure the length of the bag from the bottom left corner to the bottom right corner. This will give you the lenth of the bag.
Measure the height of the bag from the opening of the bag to the bottom. This will give you the height of the bag.
Measure the width of the bag by placing the tape measure or ruler inside the bag and measuring from the front to the back. Alternatively, simply measure from the outside back edge to the front edge.
Finally, measure the distance from the highest point of the handle(s) to the opening of the bag. This will give you the drop measurement of the bag.

Sizes can vary from 2-3 centimeters because they are measured by hand. 1inch=2.54cm The size matched on a guide can differ slightly from the one you have ordered.
