How to Order Custom Boxes: Sizes, Quantities, Artwork and Samples

If this is your first custom packaging order, the process is simpler than it looks. This guide walks through the four decisions every order needs — size, quantity, artwork and sampling — so your quote request is right first time.

A range of custom printed boxes in different sizes and styles

1. Size: measure the product, not the box you imagine

Box dimensions are quoted as length × width × depth, internal. Measure your product, then add clearance — a few millimetres for a snug carton, more if an insert or protective wrap sits between product and box. If you already have a box that fits well, measure its internal dimensions and send those. When in doubt, send the product measurements and let us recommend the box size; a box specified too tight is the most common first-order mistake. If you are still choosing between formats, see our guides on rigid boxes vs folding cartons and kraft vs white board.

2. Quantity: order what you will use, not the biggest tier

Unit price falls as quantity rises because set-up work is spread over more boxes, but that only helps if you actually use them. Rebrands, ingredient changes and address changes can all strand old stock. A sensible first order covers your realistic sales window plus a margin, and reorders are straightforward once the specification is proven. Tell us the quantity you genuinely need and we will let you know what is workable, so a new brand does not have to gamble on a pallet of boxes.

3. Artwork: dielines, bleed and print-ready files

Once the box style and size are agreed, you design onto a dieline: a template showing every panel, fold and glue area of your exact box. Artwork should be supplied in CMYK, with text and logos kept inside the safe area and backgrounds extended past the trim line (this overhang is called bleed). If that sentence meant nothing to you, that is fine. We can supply the dieline, set your logo and colours onto it, and send a proof to approve before anything is printed. Ask about design support when you request your quote.

4. Samples: when to ask and what kind

"Can I get a sample?" is the question we hear most, and the answer is yes — there are two kinds. A stock or previous-work sample shows board quality and print standard quickly. A pre-production sample of your own box proves the exact size, fit and artwork before the full run. For a first order, straightforward cartons are often fine to approve from a digital proof; rigid boxes, inserts and anything with a critical product fit are worth a physical sample. Ask for one in your quote request and we will advise which kind your job needs.

Common questions

What information do you need for an accurate quote?
Five things: box style (or the product it needs to hold), internal dimensions, quantity, any material preference, and the print or finish you have in mind. Attach artwork or a logo if you have it, but a rough brief is enough to start.
I do not have print-ready artwork. Is that a problem?
No. Send us your logo and brand colours and we can set the artwork up on the correct dieline and send a proof for your approval before print. Ask about design support when you request your quote.
How do reorders work?
Once your specification and artwork are approved, reordering is straightforward. We keep the specification on file, so a reorder is usually just a matter of confirming the quantity and any changes.
