Poly Bag Size Calculation Guide

**For Lining a Box**

- Measure the width, depth and height of the box to be lined. The depth should be the shorter side.
- To determine the Width (W) of the bag, add 1" to the width of the box.
- To determine the Depth (D) of the bag, add 1" to the depth of the box.
- The Length (L) of the bag is determined by adding the depth plus 1" to the height plus 1". Add another 5" to allow coverage of the box contents.

**Example:**

If the box size is 18"(wide) x 12"(deep) x 14"(high), the bag dimensions are as follows: Width (W) is 19" Depth (D) is 13" Length (L) is 33"

**For a Round Container**

- Measure the diameter and height of the container to be lined.
- To determine the Circumference (C) of the container, multiply the diameter by 3.14.
- To determine the Width (W) of the bag, divide the Circumference (C) by 2. Add 1" for a looser fit.
- To determine the Length (L) of the bag, add the diameter to the height. Add 5" for overhang.

**Example:**

If the container size is 12"(diameter) x 30"(height), the bag dimensions are as follows: Width (W) is 20" Length (L) is 47"

**For a Square Container**

- Measure the width, depth and height of the container to be lined. The depth should be the shorter side.
- To determine the Width (W) of the bag, add the width and depth. Add 2" for a looser fit.
- To determine the Length (L) of the bag, add 1/2 the depth to the height. Add 5" for overhang.

**Example:**

If the container size is 14"(wide) x 10"(deep) x 32"(high), the bag dimensions are as follows: Width (W) is 26" Length (L) is 42"

**For a Pallet Cover**

- Measure the width, depth and height of the pallet to be covered. The depth should be the shorter side.
- To determine the Width (W) of the cover, add 1"-2" to the width of the pallet.
- To determine the Depth (D) of the cover, add 1"-2" to the depth of the pallet.
- The Length (L) of the cover is determined by adding 1/2 the depth to the height.

**Example:**

If the pallet size is 40"(wide) x 36"(deep) x 50"(high), the cover dimensions are as follows: Width (W) is 42" Depth (D) is 38" Length (L) is 68"
