What thickness card do I need to make gift boxes?

For making gift boxes, a thickness of 250 to 350 gsm (grams per square meter) cardstock is typically recommended. This weight provides enough sturdiness to hold the shape of the box while still being manageable for folding and cutting. If you're making larger boxes or require extra durability, consider using a thicker cardstock, around 400 gsm. Always test a sample to ensure it meets your specific needs.
