This can also be done with a sewing tape measure.
You may want to cut the string at this location to make measuring easier.
Your measurement needs to be accurate down to 1⁄8 inch (0. 32 cm). If you used a sewing tape measure, you can skip this step.
21. 125–21. 5 inches (53. 66–54. 61 cm) = Small or sizes 6 ¾ - 6 ⅞. 21. 875–22. 25 inches (55. 56–56. 52 cm) = Medium or sizes 7 - 7 ⅛. 22. 625–23 inches (57. 47–58. 42 cm) = Large or sizes 7 ¼ - 7 ⅜. 23. 5–23. 875 inches (59. 69–60. 64 cm) = X-Large or sizes 7 ½ - 7 ⅝. 24. 25–24. 625 inches (61. 60–62. 55 cm) = XX-Large or sizes 7 ¾ - 7 ⅞. 25–25. 375 inches (63. 50–64. 45 cm) = XXX-Large or sizes 8 - 8+.
You can also do this with hats you have at home.
This isn’t an exact science. There will be some variation from brand to brand.
If you don’t want to do this yourself, an associate at your local hat shop can probably do it for you. The hat lining attaches to the sweatband of the hat. Hat lining is generally not removable. Attempting to remove it yourself could damage the hat.
