How many layers can I stack?

The calculator subtracts pallet base height from the loaded-height limit and divides the remaining height by carton height, rounding down to whole layers.

Does this check carton crush strength?

No. Maximum safe stacking height can be lower because of compression strength, stability, transport vibration or customer requirements.

Do I need an account to use this calculator?

No. CargoToolsHub calculators run in your browser and do not require a signup.

Should I verify the result before booking freight?

Yes. Use the result as a planning aid and verify carrier-specific rules, equipment limits, tariffs or contractual requirements before a critical shipment.

Use this calculator when you already know the carton height and need a quick vertical stacking check for a pallet specification.

How to use this calculator

Enter carton height, pallet base height and the maximum allowed loaded height. Use the same measurement unit for all three values.

Formula and method

Available stacking height equals maximum loaded height minus pallet base height. Complete layers equal available stacking height divided by carton height, rounded down.

Worked example

With a 15 cm pallet base, 160 cm maximum loaded height and 25 cm cartons, 145 cm is available for cartons, so five complete layers fit and 20 cm of height remains unused.

What to check before you ship

Maximum geometric layers can still be unsafe. Check carton compression strength, stack pattern, product damage risk, pallet stability and customer or carrier height limits.

Why the result matters

Accurate dimensions and weights help with quoting, space planning and avoiding preventable adjustments. Always use the packaged outside dimensions that will actually be tendered for transport, and verify any carrier-specific rules that affect billing or classification.
