The Collar Sets the Box
A shirt box can have the right length and width and still be too shallow. The collar often creates the highest point in the finished fold, especially with dress shirts, formalwear and structured uniform shirts.
Custom Shirt Boxes should therefore be sized around the exact folded shirt, with the collar sitting naturally rather than being pressed flat to make the lid close. Excess pressure can disturb the presentation before the customer even lifts the shirt out.
That is what separates this requirement from broader Clothing Boxes. General folded apparel can vary widely in shape. A shirt box works best when one deliberate fold, collar position and front-facing presentation are repeated consistently.
Set the Collar Height
Fold the real shirt and let the collar sit as it will during packing. Measure the total resting height instead of pushing the garment down.
Spread collars, button-down collars and heavier formal collars can create different profiles. Collar stays and internal supports can add more height again. These details should be included before the box depth is fixed.
A few millimetres of sensible headroom are more useful than a lid that visibly presses onto the collar. Too much depth creates the opposite problem, leaving the shirt looking lost inside the carton.
Allow a Clean Lift-Out
The shirt should lift without cuffs or fabric scraping tightly against the walls. This matters particularly with rigid or closely fitted two-piece boxes where the internal dimensions do not flex much.
The goal is controlled clearance, not loose space. Customers should be able to remove the shirt without disturbing the collar or pulling hard on the tissue beneath it.
