Measure the finished set, not only the headline product.
Record length, width, height and weight, then add the pieces that change the internal fit: inserts, instruction material, wrapped components, dividers, protective packing and any multi-item arrangement. For a card deck or game, measure the complete set as it will be packed. Explain how much clearance is acceptable and whether the contents need to stay in a fixed position.
Consider a folding carton when the structure starts as a flat dieline.
A folding carton is often considered for product presentation, smaller retail items and some deck or accessory formats. Its suitability depends on the contents, required protection, opening and closure direction, packing route and the information that must appear on the panels. The confirmed structure and template come before final artwork, especially where folds, glue areas, codes or small type matter.
Consider a rigid gift box when the presentation is part of the product.
A rigid gift or presentation box can be a sensible direction when the opening experience, retained packaging or internal arrangement is central to the brief. Describe what the recipient sees first, how the contents should sit, whether an insert or sleeve is needed and what must survive transport. The final construction, finish and insert approach are confirmed for the project rather than assumed from a reference image.
Consider a game box when several components need to stay together.
A game box starts with a bill of materials: boards, cards, tokens, dice, rules, bags, trays, inserts and any packing direction. Internal volume alone is not enough; the arrangement, opening sequence and storage use affect the brief. Keep component files separate from box artwork and do not treat a cover mock-up as evidence that the complete set will fit.
Ask for the right next decision.
Before a final dieline or proof stage, confirm the contents, internal dimensions, weight, protection needs, intended presentation, quantity, artwork status and delivery destination. If a requirement is still open, state it clearly so the written quote can identify what needs checking rather than silently assuming it.
