The formula for calculating the overlap at the closure of a can is as follows:

Overlap = LGc + LGf + 1.1 Gf – Lc

Where:

• LGc: Length of body hook
• LGf: Length of bottom hook or cap
• Gf: Thickness of bottom or cover material
• Lc: Length of closure

This formula allows you to estimate the overlap at the closure, although it is worth mentioning that direct measurement using a closure projector is usually more accurate. However, the formula is accurate enough to evaluate closure in most cases.
