If you're preparing to buy an Apple Watch, you need to take into consideration wrist size and the available band options to get the best fit. There are a few Apple Watch bands that need specific sizing, and others that are not designed to fit all wrists.
You can try on an Apple Watch band if you have an Apple retail store nearby, but if you don't, there's a little more measuring to do so Apple doesn't send you the wrong size. CT02-1 machine prdouct
This guide walks through all of the different Apple Watch band options and is designed to help make sure that you get the best Apple Watch band size for your wrist.
When choosing a band, it's useful to measure your wrist as a first step. If you have a cloth tape measure on hand, you can wrap it around your wrist to get your band size. For those who don't have a cloth tape measure, you can take a piece of string and wrap it around your wrist, using a standard flat measuring tape or ruler to measure the part of the string that fits around your wrist as a watch would.
Make sure that you're using string or a measuring tape that does not have give so you can't stretch it and cause an error in measurement. If you don't have a tool like this, it's best to use a piece of paper. Cut a piece of paper into a strip and wrap it around your wrist where you might wear a watch, and use a pen to mark the paper strip where it overlaps.
When doing these measurements, make sure the tape measure, string, or paper is fit tightly to your wrist and that it is not sliding around. For all Apple Watch bands, you want a snug fit that will keep the Apple Watch against the skin for sensors to function.
If your tape measure only measures in inches, you may need to convert the measurement to millimeters to best match how Apple offers its sizing guidelines. One inch is equal to 25.4 mm, so if your wrist is seven inches in circumference, multiply by 25.4 to get 177.8 mm. Siri can provide a quick conversion for you if you need it.
Apple offers the Apple Watch Series 9 in 41mm and 45mm size casing sizes, the Apple Watch Ultra 2 in a 49mm size, and the Apple Watch SE in 40 and 44mm size options. The first step in choosing an Apple Watch band is to select the right-sized Apple Watch.
Of course, those with smaller wrists will want to opt for the smaller Apple Watch options, while larger wrists will need the bigger models. The 40/41mm Apple Watch models are designed to fit wrists sized 130 to 200mm, while the 44/45mm Apple Watch models are sized to fit wrists between 140 and 220mm. The Apple Watch Ultra 2 is able to fit wrists sized from 130mm to 210mm.
Note that this guide references the 40, 41, 44, and 45mm size options available with the modern Apple Watch "Series" models, but this fit guide also works for the older 38 and 42mm models as band compatibility has remained the same since 2015.
Once you've picked your appropriate Apple Watch size, you can delve into bands and the different fits of each one. We'll explain the materials of each watch band and how they might feel on the wrist.
Not all Apple Watch bands are available in every size, and not all bands are compatible with both models. The Modern Buckle, for example, is limited to the 40 and 41mm models, but for the most part the Apple Watch bands fit a wide range of wrist sizes. There are also bands that are designed specifically for the Apple Watch Ultra 2.
The Solo Loop and Braided Solo Loop are Apple's two bands that have no clasp. The Solo Loop bands are offered in twelve sizes rather than having an adjustable loop or clasp, so it's important to measure well for these bands.
Smaller Apple Watch models are compatible with bands sized one to nine, and larger Apple Watch models are compatible with bands sized four to 12, with specifics on those measurements below. Getting the right fit for a band that does not have a clasp is tricky. For an error-free experience, this is a situation where it's best to visit an Apple Store in person to see what feels best on your wrist.
Apple offers a measurement tool online [PDF], and it's the next best tool to use if you can't get to an Apple Store. On the store page for the Solo Loop that you want, click the "Start your measurement" option to download and print Apple's sizing tool.
If you don't have a printer, you can measure your wrist with a piece of paper as described above and then use Apple's on-page calculator to determine your size. We have a dedicated guide on how to properly measure your wrist for the Solo Loop and Braided Solo Loop.
Even with the tool, some Apple Watch Solo band users have not gotten the right fit, which is again why we recommend trying the band in a store if possible. Apple does, however, offer free returns and exchanges if you do get a band that doesn't fit right.
The Solo Loop is made from a soft liquid silicone rubber, while the Braided Solo Loop is made from polyester yarn braided around silicone thread. Both of these bands have an elastic quality that allows them to slip over a hand and contract on a wrist, and these bands will stretch over time, so it may be worthwhile to size down from your measured size.
The Sport Band is an adjustable band made from a fluoroelastomer, and it comes in two sizes to fit the smaller and larger Apple Watch models. Because this band has holes for an adjustable fit, you just need to make sure that the size range below matches the size of your wrist.
Apple ships the Sport Band with components that allow it to be configured for either an S/M or M/L fit, so you will get an extra piece with a Sport Band.
Fluoroelastomer has a soft touch feel, but it is a silicone-like material. It is waterproof and sweatproof, and it does not have stretch.
Apple's Sport Loop is made from woven nylon with a hook and loop fastener. One side is a velcro-like material that adheres the Sport Loop tightly to your wrist. It doesn't use holes like the Sport Band, so you can get an even more customized fit
The Sport Loop is soft and breathable so it's comfortable when sweating, but you probably won't want to get it wet so it's best for activities without water exposure. It comes in two sizes for the smaller and larger Apple Watch models, and if you have a larger wrist, this is one of the bands with the widest fit range.
For this band, Apple says that sizing starts at 130mm, but there is some leeway here because of the wrapped fit so this is also a good choice for smaller wrists.
Apple in 2023 announced a new range of bands made of a textile called "FineWoven," which is made of 68 percent post-consumer content and is overall more environmentally friendly compared to the company's previous line of leather accessories, which Apple has discontinued.
The FineWoven Magnetic Link has a wraparound fit with the end of the band secured to the wrist using flexible, moulded magnets. The fit is not unlike the Sport Loop, but with a "durable micro-twill" material instead of woven nylon. Bear in mind that FineWoven cases for iPhone 15 models have been heavily criticized since they were released earlier this month, with some customers and media outlets complaining that the material is very susceptible to visible scratches and stains.
With a wrap fit, the only consideration when choosing this band is to make sure your wrist falls in the size parameters listed below.
Made from FineWoven material, the Modern Buckle is Apple's only band that is exclusive to the smaller 41mm Apple Watch models. It is not compatible with the larger 44 and 45mm Apple Watches.
The Modern Buckle has a buckle clasp and the fit is not quite as forgiving as some other bands, so you need to make sure that you buy one that's appropriate for the size of your wrist. There are three sizes, starting at 135mm, so this band starts out a little bit larger than some other Apple Watch bands.
Sizing maxes out at 180mm, so if you have a wrist that's over seven inches, you'll want to go with a different band. The Modern Buckle is another band that's more for fashion than function, and it isn't designed to get wet.
The Milanese Loop is made from a stainless steel mesh, and it has the same wraparound design as the Sport Loop. Like most Apple Watch bands, sizing starts at 130mm, but it's worth noting that this is one of the smaller Apple Watch bands, topping out at 200mm. If you have a larger wrist (Over 7.8 inches), the Milanese Loop may be too small.
The Milanese Loop is a fashion band and it is not meant to be used for exercise nor is it meant to get wet, but it won't soak up water like the Sport Loop if it does get water on it.
Made from a stainless steel alloy, the Link Bracelet is Apple's most expensive band, with a link design that looks similar to a high-end watch band. Sizing can only be adjusted by removing links, so there's less flexibility with the Link Bracelet than with other bands.
Sizing on the Link Bracelet starts at 135mm so it's a bit bigger than some other Apple Watch bands, and it maxes out at 200mm, so the size range is smaller than other options. Because of the way it fits, you're going to want to make sure you're right within the size measurements listed below.
Links can be removed or added with a release button, so it's not too tough to adjust the size once you purchase this band.
Apple offers three bands designed for the Apple Watch Ultra 2. Still, Apple's website does note that the bands are compatible with 44mm and 45mm case sizes of previous generation Apple Watch models.
First is the Alpine Loop, which comes in Blue, Indigo, and Olive. This band is made from two textile layers woven together into one continuous piece.
Next is the Trail Loop in Green/Gray, Blue/Black, and Orange/Beige. It also costs $99.00 and is made from a soft nylon weave with a pull tab for quick adjustments.
Last is the Ocean Band in Blue, White, and Orange. It's molded in a high performance elastomer with tubular geometry allowing it to stretch to a perfect fit, even over a wetsuit.
In fact, the 49mm Apple Watch Ultra 2 will work with most existing Apple Watch bands, according to Apple's website. The device is compatible with bands designed for the larger 42, 44, and 45mm case sizes available for the Series 8 and older Apple Watch models.
For the most part, every Apple Watch band has a good size range, and you really only need to pay close attention if your wrist is smaller than average or larger than average.
Wrap bands like Sport Loops are the most forgiving in both situations, and if you have a large wrist the Sport Band and Sport Loop may fit where other bands do not. For small wrists, the Sport Loop can be pulled tight and it will offer a better fit than something like a Sport Band.
Sizing is especially tricky with the Solo Loop and Solo Braided Loop, so measurements for these watches need to be spot on. You don't need to be quite as careful with the other Apple Watch bands, but it is useful to get precise measurements to ensure a good fit.
With any of the bands, it's a good idea to go to an Apple retail store if you can for a try-on process so you can get an idea of the different materials and what they feel like on the wrist. This can be especially helpful with the Solo Loop and Solo Braided Loop because the measuring tools aren't accurate for everyone.
With almost all of the bands, the fit is true to size, but the Solo Loop and Solo Braided Loop stretch, so with these two bands, you might want to size down.
