What Size Body Armor Plates Do I Need? A Full Sizing Guide
Finding the correct size for your hard plates is crucial to provide proper coverage and prevent immobility. There are a few ways to help determine your plate size, all of which are pictured below.
- Height: People under 5' 2" are best suited for 8x10 and Small SAPI plates. Women more commonly will fit better in an 8x10. For the majority of people, 10x12 or Medium SAPI (9.5x12.5) plates provide the right amount of coverage without hindering your mobility. This includes people all the way from 5' 3" to 6' 4". If you're on the taller end of this range but without a large chest, Large SAPI might be a better fit. People 6' 4" and taller are likely ready for 11x14 or XL SAPI plates. Remember, with larger sizing comes greater weight load.
- Chest Circumference: Measure around your chest at the level of your nipples to chest measurements. 10x12 plates will fit a majority of people and Medium or Large SAPI plates can help attain an even closer fit when you are on the lower or upper end of the measurement range.
- Quick Torso Test: Measure the distance from the center of one nipple to the other. This is roughly your plate width. Measure the distance from your sternum notch (the area right above where your collarbones meet) down to your belly button and subtract roughly 2-3 inches or about 3 fingers length. This is roughly your plate height.
