How are bags measured?

Bags measurements are expressed as the entire width x height (9x12, 15x18, etc) of the flattened bag. If bag has side gussets, the measurement is written as Width x Gusset x Height (12x7x22 is a standard T-shirt bag). If bag has a bottom gusset, the measurement is written as Width x Height + Gusset Width (15x18+4"BG for instance).

It's important to understand that bags with side gussets always have a bottom seal, and bags with bottom gussets will have a side seal. 

Bottom Seal bags are sealed between 1/4" and 1/2" from the very bottom of the bag, while side sealed bags are sealed at the very side edges. 

The height of the bag is measured from the very bottom of bag to the very top, except for Soft Loop Handle bags where the handle is attached and not included in the height measurement.
