Fold Height Defines the Box
Rigid apparel packaging should begin with the garment after it has been folded for sale, not with the dimensions of the garment when worn.
A medium shirt, heavyweight sweater and coordinated lounge set can occupy very different volumes even when their retail size labels appear similar. Fabric thickness, fold count, collars, trims and included accessories all change the packed height.
That makes internal depth one of the most important decisions for Custom Rigid Apparel Boxes.
Across retail and apparel packaging, rigid construction makes sense when folded garments need stronger shape retention and a more stable interior than a lightweight carton can maintain.
Measure the Real Retail Fold
Do not estimate box depth from clothing dimensions on a specification sheet.
Fold the actual garment the way staff will pack it. Add tissue, a garment board, care card or accessory only if those components will be present in production.
Then measure the finished stack.
A box specified before that packing sequence is settled can end up compressing the garment or leaving excessive vertical space.
Fabric Loft Changes the Result
A fine dress shirt compresses differently from knitwear.
A sweatshirt or heavy sweater may rebound after being pressed into a shallow box. That pressure can make the lid sit high, distort tissue or create an inconsistent closed profile across units.
Rigid walls hold their shape, so the garment cannot simply push the package outward as it might with a softer pack.
Depth needs to absorb normal variation in the folded apparel without becoming unnecessarily tall.
