Control Edge Impact
Cookies usually fail at the edge before the center. A box can look spacious and still create breakage if cookies slide far enough to strike a wall or another piece.
Start with the finished diameter, thickness and decoration profile. Then decide how much lateral movement the pack can tolerate. The goal is controlled clearance, not a tight squeeze.
Protect the Rim
Round cookies often need restraint close to the lower edge rather than pressure across the top surface. A shallow tray, divider or correctly sized compartment can reduce impact without crushing decoration.
Stop Long Sliding Paths
Large empty areas allow a cookie or stack to build momentum. Break that movement with count-appropriate geometry rather than filling space randomly.
Edge impact becomes more important as cookie diameter increases because a larger disc can gain more momentum across the same empty space. Check the most fragile variety in the assortment and use that behavior to set the allowable movement.
Cookie edge strength can vary by recipe, bake time and inclusions. Large chocolate chunks, nuts or very crisp rims may create local weak points, so a fit that works for one SKU should not automatically be copied to every cookie sold in the same count.
