Size & Safety Guide

Find Your Fit.
Know Your Standards.

Everything you need to order the right hat with confidence — sizing, ANSI classes, and how to read your certification label.

Step 1 — Measure

How to Find Your Hat Size

Hard hat sizing is based on head circumference, measured just above the ears and eyebrows. Here's how to do it in 30 seconds.

📏

Get a Flexible Tape

Use a soft measuring tape or a piece of string you can measure against a ruler afterward.

🔄

Wrap Above Your Ears

Position the tape about 1 inch above your ears and eyebrows — the widest part of your head.

✅

Match the Chart Below

Note the measurement in inches or centimeters and find your size in the table below.

Hat Size	Inches	Centimeters	Common Fit
6½	20⅜"	51.8 cm	XS
6¾	21¼"	54.0 cm	S
7	22"	55.9 cm	M
7¼	22¾"	57.8 cm	M–L
7½	23½"	59.7 cm	L
7¾	24⅜"	61.9 cm	XL
8	25⅛"	63.8 cm	XXL

💡 Pro tip: Most of our hats use an adjustable ratchet suspension that fits sizes 6½ to 8. If you're between sizes, go with your measurement — the ratchet will dial it in perfectly on site.

Step 2 — Choose a Type

What Type & Class Are Our Hats?

All our hats are ANSI/ISEA Z89.1 Type I certified — meaning top-impact protection, the standard for virtually all construction and industrial job sites. We offer three electrical protection classes to cover every trade.

Type I — What We Carry

Top-Impact Certified

All our hats are ANSI/ISEA Z89.1 Type I certified. Type I protects against impacts to the top of the head — the standard for virtually all construction, manufacturing, and industrial job sites. OSHA approved.

Class C, G & E

Three Electrical Classes

Within Type I, we offer all three ANSI electrical protection classes: Class C (no electrical protection), Class G (up to 2,200V), and Class E (up to 20,000V). Check the product listing for the specific class.

Type II — By Request

Available on Demand

Type II (top + lateral impact protection) is not in our standard catalog but may be available for bulk or crew orders with sufficient demand. Contact us if your site requires Type II.

Step 3 — Know Your Class

Electrical Protection Classes — We Carry All Three

ANSI/ISEA Z89.1 defines three electrical protection classes within Type I. All our hats are available in Class C, G, and E — check the product listing for the specific class you need.

Class	Voltage Protection	Who Needs It	Available From Us?
Class E (Electrical)	Up to 20,000 volts	Electricians, lineworkers, utility crews	✓ Yes — we carry Class E
Class G (General)	Up to 2,200 volts	General construction, most trades	✓ Yes — we carry Class G
Class C (Conductive)	No electrical protection	Non-electrical environments only	✓ Yes — we carry Class C

⚡ Electricians: OSHA 29 CFR 1926.100 requires a Class E rated hat for electrical exposure above 2,200 volts. We carry Class E — look for it in the product listing. Always confirm with your site safety officer before ordering.

Keep It Looking Sharp

How to Care for Your Hat

The hydro-dip finish is built tough, but a little maintenance goes a long way.

🧽

Clean with Mild Soap

Wipe down with a damp cloth and mild dish soap. Avoid harsh solvents — they can dull the clear coat.

🚗

Keep Out of Hot Cars

Prolonged heat above 120°F (49°C) can warp the shell. Don't leave it on a dashboard or in a parked car.

📅

Replace Every 5 Years

ANSI recommends replacing hard hat shells every 5 years regardless of visible condition. Mark your purchase date inside the hat.

💥

Replace After Impact

If your hat takes a serious hit — even without visible damage — replace it immediately. The internal structure may be compromised.
