Watch straps only come in four sizes: short, standard, long, and extra long. That should make it easy to find the perfect fit for your hand, right?
It turns out that watch straps are a little bit more complicated than that. Measuring your watch band is necessary to ensure that replacement straps fit just as well as or better than the existing strap. Doing so helps you to get the lug width and strap length just right.
The process of measuring your watch band is easy and fun. Strap on, grab a string, ruler, or calipers if you have them, and let's do this.
You would be surprised at how many people don’t know how to wear a watch right even when it feels or looks wrong. For example, should you wear your watch below or above the wrist bone? Do you know how big the bands should be in relation to your wrist?
The following guidelines reflect the general consensus on what is considered the ideal fit for a watch.
Watch band makers do not make it easy for buyers to find the right band size. For starters, the standard watch band classifications provide little information to help the average buyer.
This chart with common watch band sizes and classifications should help you get started.
Apart from the general watch band size classifications, the length of watch straps is expressed in two numbers. The first and the larger one represents the length of the tail section, while the other smaller number is the length of the buckle section.
|Watch Band Size Classification||Watch Band Length in Inches||Band Size in Millimeters||Women’s Watch Band Sizes|
|Regular/standard length||7 ¼” to 7 ½”||120 mm/80 mm||6 ½” to 6 ⅖”|
|Short/small length||6 ½” to 6 ¾”||110 mm/70mm||5 ¾” to 7 ⅕”|
|Long length||8 ¼” to 8 ½”||130 mm/90 mm||7 ¼” to 8”|
|Extra-long length||9 ¼” to 9 ½”||Above 130 mm/90 mm|
Not all manufacturers abide by this convention. Some watch band makers such as Hirsch have their strap sizes ranging from medium to extra-large, but the strap length remains largely the same.
Watch bands are also sized by their lug width. The most common widths range from 18mm to 28 mm (5/16” to 1 1/10”). Sellers and manufacturers prefer to present strap width in millimeters, as this conversion chart will show.
|Strap Width in Millimeters||Strap Width in Inches|
The width of the strap can go as low as 6mm to as large as 30mm. To convert other lengths to and from the metric system (mm), simply multiply or divide by 25.4, respectively.
Measuring your wrist size and watch case gives you the band length and width dimensions that you need to find the ideal strap for your watch.
The tools you will need to use in either case are simple: a piece of nylon string, a standard ruler calibrated in inches and centimeters, and optional digital calipers.
If you have the old straps that fit perfectly, here is what to do.
If you need to measure from scratch:
What this measurement gives you is the ideal length of the strap to the hole on the strap where you expect the prong to go. In practice, the measurement won’t be so precise, so adding an inch or two to the number you get here will give you the right number.
As we have mentioned before, the width of your strap is the same as the lug width of your watch.
The strap should fit snugly between the lugs with no excess space. According to the table above, the lug width should be a nice round number such as 18mm, 20mm, 22mm, and so on.
In addition, the band type you want to buy will affect the size of strap you choose.
Pass-through or slip-through straps go under the watch to cover the whole wrist, so you won’t need to subtract the watch case length from your wrist size. However, an extra length of material is threaded through the watch to hold the watch in place.
The total length of the pass-through strap should be about 1” or 25 mm larger than your wrist size to account for this extra material.
A leather strap is the quintessential option for a dress watch, which is also why it’s the perfect gift choice for watch lovers. You should allow for 2cm or about an inch more than the total length of the straps and watch case.
When sizing leather watch bands, defer to the measurements of the existing leather strap whenever possible. This will give you the exact size of your watch strap with a lesser possibility of ending up with a short strap.
Finding quality leather and slip-through watch bands is not so easy, though. BluShark straps are designed for extreme durability, soft-fit comfort, and a delightful texture.
More importantly, our online shop gives you complete sizing information to ensure that you choose the right option for the perfect fit.
Sizing a watch with a deployant clasp is very similar to any other watch strap, but with two important differences.
The first is that the length of the clasp itself is not factored in the total length of the strap. Secondly, these clasps tend to have a shortening effect on the strap, so you will want to err on the longer side when choosing the ideal fit.
Metal bracelets are worn a little looser than pass-through or leather straps to allow for more fluidity in movement. For this reason, the length of the bracelet and watch case should be one centimeter larger than your wrist measurement.
Measure your wrist using a tailor’s tape measure or a string to get an accurate wrist measurement for a metal bracelet. Most new bracelets do have some removable links for resizing, but it’s best to stick to the sizing guide for minimal inconveniences.
Sizing your watch strap perfectly is deceptively simple, isn’t it? Manufacturers and sellers don’t make it easy as well, but now you should be ready to order watch bands online.
If you get it wrong, the strap will have plenty of room for adjustment. Where you can’t afford to err, though, is on the quality of your watch strap.
Poor quality straps just feel and look wrong, not to mention that they can chafe and irritate your skin. Get all your watch straps from BluShark Straps and be assured of top quality every time.
