Choosing A Watch for Your Wrist Size

Find a watch that beautifully fits your wrist with Heller Jewelers in San Ramon, California.

Watches are available in all shapes and sizes. From prominent cases to slender bands, designers offer a wide selection sure to cater to any taste. However, some pieces are more suited for certain wrist sizes than others. To create a unified and appealing look, one should follow our guide to ensure their watch matches their wrist.

Find Your Measurement

The first thing you’ll want to do is get an accurate measurement of your wrist. Use a tape measure that can wrap completely around your wrist. Make sure you have a writing utensil handy to write down the number.

Pick a favorite wrist and rotate your arm outward. When the palm is facing up, open your hand. This is when your wrist will be the largest. While it’s tempting to rotate your wrist inward as if you’re reading the dial, the timepiece should fit at any moment.

Now, place the end of the tape on the middle of your wrist. It should sit on the wrist bone or a half-inch higher, towards the elbow. Finally, wrap the tape firmly (but not too tightly) around the wrist. There should be no space between the tape and the skin. Match the marks and now you’ve got an accurate measurement.

Find Your Strap

Watch straps deeply impact a timepiece’s overall aesthetic. The color, texture, and material should complement the case. It is essential to make sure the strap matches one’s wrist size. Not only does it look better, but it ensures that the timepiece fits comfortably. First, you’ll want the strap’s width to be about half that of the case. So, if a watch is 44 millimeters in diameter, make sure the strap is 22 millimeters.

When it comes to the length of the strap, it’s a little more complicated. For example, if your wrist size is 7.1 to 7.5 inches, get a strap that’s 130/80 millimeters. You may notice that the length is in two dimensions. The first refers to the tail side strap, while the second is the length of the buckle side strap. The former is always longer. It’s probably best to look for a chart online or call us at (925) 904-0200 to learn more.

Find Your Case

Note that you can wear any watch. If you have a thick wrist and like the look of a thin watch, then wear it! However, those who prefer to have a piece in proportion to their wrist size may want to match their watch to their wrist.

A 6-inch wrist is considered small, as is anything thinner. Average wrists are between 7 to 7.5, while thick wrists are larger than 8. Watch cases are generally measured in millimeters: 6 to 8 mm is small, 8 to 12 mm is average, and 12 to 18 is large.

All in all, it depends on you. If you have any questions about watches that fit, book an appointment with us.
