Protect the Macaron Feet
The ruffled foot around a macaron can chip before the centre of the shell shows any obvious damage. That makes contact pressure more important than simply choosing a box that looks snug.
Custom Macaron Boxes need to stop rolling and sideways movement without squeezing the shell edges. A cavity that is too loose lets each piece gather speed when the carton tilts. One that is too tight can put pressure on the very part the insert is supposed to protect.
Use the Filled Thickness
Measure the finished diameter and total thickness after filling, not the empty shells before assembly. Ganache, buttercream and other fillings can change the final thickness enough to affect row length, cavity width and lid clearance.
If several flavours use the same box, measure a realistic sample from each recurring flavour. The aim is to find the working size band rather than build the insert around one unusually small macaron.
The custom product packaging approach follows the same principle: size the packaging around the finished product as it is actually packed.
Support Without Pinching
The insert should restrain the macaron through stable contact points while leaving the fragile shell surface free from hard compression. Do not solve movement by making every cut-out aggressively tight.
A small amount of controlled tolerance helps staff load the set without twisting the macarons into position. The exact allowance depends on product variation, insert material and whether the macarons sit flat or on edge.
