Request Custom SizesHow to Measure Your Boxes
Understanding the L × W × H convention and measuring correctly helps you request the right size.
Length (L)
The longest side of the box opening. Measure from the longest edge of the open top.
Width (W)
The shorter side of the box opening. Measure from the shorter edge of the open top.
Height (H)
The distance from the bottom of the box to the top. Also called the depth.
Inside vs. Outside Dimensions
Box dimensions are typically listed as inside dimensions — the usable space inside the box. Outside dimensions will be slightly larger depending on the wall thickness.
- Single wall: adds approximately 1/4" per side (1/2" total per dimension)
- Double wall: adds approximately 3/8" per side (3/4" total per dimension)
- Triple wall: adds approximately 1/2" per side (1" total per dimension)
Measuring an Existing Box
To determine the size of a box you already have, follow these steps:
- Open the box fully and lay the flaps flat.
- Measure the inside length at the longest opening edge.
- Measure the inside width at the shorter opening edge.
- Measure the inside height from the bottom panel to the top of the side wall.
- Look at the cut edge of a flap to see the wall type, and check the box maker's stamp on a bottom flap for strength ratings.
Flute Thickness Reference
Corrugated board thickness is determined by the flute profile. This affects both cushioning ability and stacking strength.
| Flute | Thickness | Best For |
|---|---|---|
| A Flute | ~3/16" | Excellent cushioning, fragile items |
| B Flute | ~1/8" | Good stacking strength, canned goods |
| C Flute | ~5/32" | Most common, general-purpose shipping |
| E Flute | ~1/16" | Retail packaging, printed boxes |
| BC Double Wall | ~1/4" | Heavy items, stacking, industrial |
How to Choose the Right Size
Selecting the correct box size is critical for product protection, shipping efficiency, and cost savings.
Measure Your Product
Measure the length, width, and height of your product at its widest points. Add at least 2 inches to each dimension to allow space for cushioning material such as bubble wrap, packing peanuts, or foam inserts.
Consider Weight Distribution
Heavy items need stronger boxes, so look at double-wall or triple-wall as the weight goes up. Distribute weight evenly inside the box and keep the center of gravity low to prevent tipping during transit.
Plan for Stacking
If boxes will be palletized or stacked in storage, factor in the compression strength needed. Heavier boxes go on the bottom. Avoid overhang past the pallet edge, which weakens the stack and increases damage risk.
Check Carrier Requirements
Each shipping carrier has maximum size and weight limits. UPS and FedEx parcel services have typically capped at 150 lbs and 165 inches (L + 2W + 2H). LTL freight has different thresholds. Verify current limits before finalizing your box size.
Understand Dimensional Weight
Carriers charge based on whichever is greater: actual weight or dimensional weight. DIM weight is commonly calculated as (L × W × H) / 139, though divisors vary by carrier and service. Oversized boxes with light contents cost more to ship, so right-sizing pays off.
Match Box to Contents
A box that is too large wastes material and allows contents to shift. A box that is too small risks damage and may not close properly. The ideal box leaves just enough room for protective packing on all six sides.
Volume & Weight Calculator
Use these formulas to plan your packaging and compare shipping options.
Cubic Feet Calculation
Where L, W, and H are in inches. Divide by 1,728 to convert cubic inches to cubic feet.
Example: A 24 × 18 × 18 box = (24 × 18 × 18) / 1,728 = 4.5 cubic feet
Dimensional Weight Formula
Where L, W, and H are in inches. A divisor of 139 is common for US parcel shipments, but some services use a different one, such as 166. Check your carrier's current rules.
Example: A 24 × 18 × 18 box = (24 × 18 × 18) / 139 = 55.9 lbs DIM weight
Estimating Box Quantity Needed
To estimate how many boxes you need for a shipment:
- Calculate the total volume of all products to be packed.
- Work out the usable interior volume of your chosen box, allowing for cushioning.
- Divide total product volume by usable box volume.
- Round up to the nearest whole number and add a few spares for breakage or packing variations.
Load Planning Tips
Maximize pallet utilization and reduce shipping costs with these load planning guidelines:
- A standard 48 × 40 pallet has 13.3 sq ft of surface area — choose box sizes that tile efficiently.
- Typical pallet height limit is 48-60 inches including the pallet itself (5-6 inches).
- A 53-foot trailer fits 26 standard pallets single-stacked (double-stacked up to 52).
- Keep total weight within the pallet's rated load and your equipment's limits for safe handling and transport.
8 Tips for Choosing the Right Box Size
Avoid costly mistakes and protect your products with these practical sizing recommendations.
Always measure your product first before selecting a box size.
Add at least 2 inches of padding on each side for cushioning material.
Right-sizing your boxes saves shipping costs and reduces material waste.
Use double-wall boxes for heavier or fragile goods.
Consider stacking strength if palletizing — heavier items go on the bottom.
Check your carrier's maximum size and weight limits before choosing.
For irregularly shaped items, measure the widest points in each dimension.
Factor in dimensional weight pricing — oversized boxes cost more to ship even when light.
