# Guidelines for Specifying Custom Bags

Poly Bag Dimensions:

The first dimension stated when describing a poly bag is the width. Flat Bags are described as width, length and gauge. Side Gusset Bags are described as width, gusset, length, and gauge. Bag measurement are inside dimensions, with the exception of shielding/barrier bags, vacuum pouch and t-shirt bags.

How to Measure for Drum Liners:

Width = (the circumference of the drum ÷ 2) +2". It is easiest to use a flexible tape measure and measure around the widest part of the drum. Length = (height of the drum + the width, or diameter) + 4". You will need the extra 4" to fold over or tie the bag.

How to Measure for Box Liners:

Width = (the circumference of the box ÷2) +2". (The circumference equals the sum of the length of each side). Length = 1/2 the narrow width + the height of the box. Add 5" to 8" extra material for fold over or tie off.

Pallet Covers:

Width = (the circumference of the pallet ÷2) + 4". The circumference equals the sum of the length of each side. Length = (1/2 the narrow width of the load + the height of the load) + 2".
