Kid’s Hat Size Chart

Kids love to play outside all day; wearing hats can make playtime less stressful and protect against mosquitoes and harmful UV rays. Children’s hats can also act as temperature regulators and keep the kids cool.

Winter hats are the water-resistant and thick fabric that protects the kids against the lashes of harsh weather. Making the kids wear a hat is a way to keep them warm and protect them from catching a cold.

Children have different head shapes and sizes. Finding the size can help you buy the right hat for your child. Get a measuring tape and wrap it around your child’s head above the ears.

Make sure to measure it straight and leave some space for movement, so it’s not tight. Lastly, round the measurement to the nearest cm to know the hat size for your child. 

Check out the hat size chart below to find out the hat size by age for a perfect fit.

Women Hat Size Chart

Hat shopping can be easy if you know the correct hat size to fit you perfectly. Stand in front of a mirror with a measuring tape and wrap it around your head.

Place the measuring tape just above your ears and then take the measurements. This is how to find the hat size for men, women, and children.

If your new hat is too big, you can use elastic bands to tighten it. You can also use customized hat reducer tape to adjust your hat to the proper density and width. Cut a two to three-inch strip, peel off its plastic and stick a hat reducer tape for a tight fit. 

If you want to improve the fair use of elastic bands, sew them onto the hat according to the size you want. First, sew it on one side and then try on the cap, then sew the elastic on the other side and tighten it according to the fit you want. Make sure to knot your stitches so that they can bare the stretch. 

If your new hat is too small and you are tired of waiting for it to break in, then you can steam, mist it, or use a hat stretcher. Moist your hat and then wear it so that it adjusts to your head size and then keep wearing it to adapt to your size.

You can repeat this procedure 3 to 4 times, and you will start noticing a change in hat size. The table below will help you find your perfect hat size in inches and the hat size in cm.

Hat Sizes For Men.

Men’s caps and hats come in sizes ranging from small to extra large, but some hats may be listed as OSFM(one size fits most). These hats are made to fit the head size of medium/large measurements 21.5 inches to 23 inches.

Actual hat sizes vary from brand to brand, and some may have different hat sizes that fit according to their style. Hence, it’s advisable to measure the hat size according to the instructions above and check the hat sizing chart for the brand you want to buy hats from.

Also, most hats are only sometimes true to the size they state, so maybe you thought you were buying the right hat to find out it doesn’t fit. Luckily, most caps have an adjustable band or drawstring so that you can adjust the fit of your hat if it’s too loose. 

Some brands manufacture hats in one size; some don’t cater to half sizes, so you must measure your hat size to the nearest inch. Consult the table below to find your size.
