How to Measure
Length — tallest dimension, from floor to top of handle/wheels
Width — widest side, including external pockets
Depth — front to back, at the thickest point
Always measure the full external size — wheels, handles, and pockets count. Manufacturer specs often exclude these.
What is the Squish Score?
Not all bags are rigid boxes. A soft bag that is slightly over the limit can still squeeze into a gate sizer if the material compresses. We rate bags from 1–5:
