How to Measure Catcher’s Chest Protector? | Sizing That Actually Fits

Measure from the base of the neck or sternum down to the navel, then match that length to the brand’s size chart.

Getting the right fit for a catcher’s chest protector comes down to one torso measurement, not age or jersey size. The tape measure method is simple, but each brand measures from a slightly different starting point, so matching your number to the right chart matters more than the number itself.

Where to Start the Measurement

The disagreement is only about where exactly to start. Wilson’s C1K and EZ Gear 2.0 guides both say to measure from the bottom of the neck to the navel. Rawlings and Easton use the top of the breast plate to the waist. All-Star’s fastpitch guidance starts at the indent at the top of the sternum, and EvoShield measures from the bottom of the neck roll down the center of the protector.

If you’re between sizes on any chart, All-Star’s own fitting advice is to select the longer length. A protector that’s slightly long still protects; one that’s short leaves your sternum exposed.

Step-by-Step Measuring Process

Grab a flexible measuring tape and follow these four steps:

• Find the starting point — locate the base of your neck where it meets your collarbone, or the indent at the top of your sternum, depending on the brand’s chart you plan to use.
• Run the tape straight down — keep it centered on your chest, following your body’s natural line to your navel or waistline.
• Write down the length in inches — this single number is what you’ll compare against the size chart.
• Test the fit in a crouch — squat into your catching stance and confirm the protector sits high on your chest, covers your throat area, and doesn’t restrict your movement.

Age ranges are only a rough guide.

Size Charts Vary by Sport and Brand

Baseball and softball use different measurement conventions and size ranges, so never swap charts across sports. Here’s how the current charts break down:

Within those ranges, individual models differ. The spread is why you always check the specific model’s chart rather than assuming one adult size fits all.

Fit Checks That Matter for Safety

A protector that measures correctly on paper can still fail you on the field. Position matters as much as length. The protector should sit high enough that the throat area is covered, and the center of the padding should line up with your sternum. If the protector rides low or shifts when you crouch, it’s not protecting what it should.

Look for certified NOCSAE padding when shopping, and keep in mind that measurement terminology varies by brand — base of neck, bottom of neck roll, sternum indent, top of breast plate — so read each chart’s instructions before measuring.
