01
Box sizes
Every box is cut to your dimensions — length, width and depth set by the product; rigid, folding and corrugated styles all follow the same measurements.

Sizes
Every box is made to your product, not to a fixed stock size. Accurate dimensions keep the product still and reduce freight.
Our sizes
Made to your dimensions
Send the product size and weight; we set the box, insert and tolerances around it.
A snug fit
Enough clearance to load and unload, tight enough that nothing shifts in transit.
Flat-pack friendly
Where the style allows, boxes fold flat to cut shipping and storage costs.
Sizing
Measure the product, not the old box.
Most size problems start with a measurement taken from the wrong object.
Measure it as it sits
Length, width and height of the item in its packaging position — not the box it arrived in.
Leave clearance
Typically 2-3 mm on each side for paper wrap and inserts, more for fabric or soft goods.
Send a photo with a ruler
Often faster than a drawing: we can see the shape and confirm the fit before a sample.

Size specs
Sizes, explained.
How sizing works at every level — from the product outline to the shelf-ready box. Exact dimensions are set on your quote.
02
Paper bag sizes
Bag width, depth and height are set around what the bag carries, with the handle length matched to the load.
03
Insert sizes
Insert cavities are cut from your product outline, with clearance added so the item loads easily and cannot shift in transit.
04
Recommended sizes
Send the product and we recommend the box style, board thickness and insert — the physical sample confirms the fit before the run.
05
Stock sizes
Mailer, round and drawer styles cover many common products straight away — and every order can still be cut to your exact size.
06
Measuring a box
Length, width and depth come from the product, not the carton: measure the item as it will sit in the box, add clearance, and the box dimensions follow.
