Armor Plate Size Finder
Convert your measurements to inches and centimeters for a plate maker's own sizing chart. Fit is the maker's chart: this page does not pick a size.

What is the Armor Plate Size Finder?
A measuring helper. Plate makers publish their own sizing charts, and the same size name can mean a different cut at a different maker. Measure the way the chart for your plate describes, enter the numbers here, and compare both units with that chart.
Until October 2026 this page picked a size from torso-height bands. It no longer does: a wrong size is a plate you believe fits when it does not, and only the maker's chart can say. If you fall between two sizes, ask the maker before you buy.
❓ Frequently Asked Questions
Why doesn't this tool pick a plate size?
Because fit is the plate maker's own sizing chart. Size names and cuts differ between makers, so a size name at one maker is not the same plate at another. This page converts your measurements so you can read the maker's chart; if you fall between two sizes, ask the maker before you buy.
How do I measure?
The way the maker's sizing chart describes. Charts differ in where they start and stop a torso measurement, so follow the one for the plate or carrier you are looking at, and have someone help you measure standing straight.
Does a bigger plate mean more protection?
This site does not say what any plate covers or protects against. The plate's label, the standard it names and the maker's sizing chart are the authority. Laws on owning or buying body armor vary by country and state; check your local law.
