So, have you decided to purchase a welding cap but are not sure what size would fit your head?
I understand the struggle of finding the perfect fit welders cap when shopping online. Because sometimes your cap can be too tight and sometimes too large to fit comfortably on your skull.
That’s why I hope my write-up on how to measure welding cap size will help ensure you get the perfect fit.
Welding Cap Measurements
Comfort is one of the main considerations while purchasing a welding cap. It should fit nicely and comfortably on your head.
You don’t want to wear a cap all day long that is too tight or too loose on your head because it may be uncomfortable, which may cause hindrance during your welding. Moreover, this headwear is meant to be protection for your head, ears, and neck from flying welding sparks.
To ensure your weld cap functions as intended, you must choose the right size cap.
A common misconception is that your weld cap size is the same as your baseball cap. This is not true when it comes to buying the right size cap for welding. Sometimes the welding cap size chart may vary, so measuring your head is important.
To figure out what size cap you need, you have to measure-
-the circumference of your head
-your crown height.
Now, let’s measure for size.
Don’t worry; it’s easy.
What you’ll need:
- You’ll only need a flexible measuring tape or tailor’s tape.
The tape must be soft.
Don’t use a metal tape measure.
If you don’t have a measuring tape, you can use a non-stretchable string.
** Do not try to measure your head with a metal tape measure!
How to Measure Welding Cap Size- Steps-By-Step Guidelines
By measuring your head circumference, you can figure out your required
finished measurement of the band of the cap.
Measuring Head Diameter
Step 1: Hold one end of the tape measure (or the string) to the center of your forehead, where you want the cap band to lay.
Step 2: Wrap the tape around your head until your return to the starting point. The tape placement should be just above your eyebrow and ears but in a position that would be comfortable for a cap to rest. It should also be over the natural bump at the back of your head.
** If you prefer your cap to cover your ears, include them in the measurement.
Ensure the tape measure is flat on your head and isn’t twisted.
Do not pull the tape too tight so that you stretch the tape. Ensure the tape is snug around your head but not too tight. It should e comfortable and just fitted enough to stay put.
Step 3: Carefully note down the measurement where the tape meets. Try to write the reading in inches as that is the most common method for measuring head circumference.
This is your weld cap size.
**Cotton welding cap may shrink after the first wash. So, check if the construction materials and come pre-washed or not.
If it comes pre-washed, you don’t need to add extra numbers thinking the cap with this measurement will shrink after wash and be tight.
** If you use a string instead of the tape measure, lay the string flat on a ruler to get the measurement.
Step 4: Use the size chart to determine which size will be your best fit. Choose the larger size closest to your actual measurement if you’re between sizes.

*Many welding cap brands have slight variations in their caps measurements and sizes.
*Not all brands include a size chart on their websites. These measurements should work for most welding caps.
Measuring Crown Height/ Cap Depth
Cap depth is labeled ‘high crown’ or ‘low crown.’
Crown height refers to the distance from the peak of your head to the band’s bottom edge.
Step 1: Measure from the highest peak of your head downwards your ears. Stops where you want the bottom edge of the band to be.
Step 2: Note down the reading.
*If you have an existing/ old cap that fits fine, lay it flat on its side. Measure the distance from the top of the crown to the bottom of the band.
Welding caps are available in different depths.
|6-1/2 inches (low crown)||It is a traditional fit that sit at the top edge of the ears like a baseball cap.|
|7-inch (Medium crown)||Covers up to the middle of the ears|
|7-1/2 inches (high crown)||Covers all of your ears|
|8-inch||If fits users whose cap size is 7-5/8” or larger|
**Everyone is different, so the same crown depth may not fit in the same way for everyone.
Brims also come in different lengths.
- 2-inch: It is the shortest brim size. It is perfect if you prefer a smaller size or don’t need a brim in your way,
- 2-1/2 inches: It is the standard brim length. It fits nearly everyone.
- 3-inch: It is a popular size. 3” brim provides sufficient coverage of neck and ear.
- 3-1/2 inches: It is perfect if your work demands a longer brim.
