Size guide


At Astra Straps, all our bands have clear and specific sizes indicated. Please check the sizing guide below before ordering. If you are still unsure, you may contact us here.

1. How do I know my wrist size?

Simply use a flexible measuring tape to wrap around your wrist and record the measurement on the tape that overlaps the zero end of the tape OR just grab any string/paper strips to do the same, then lay the string on a ruler to get your accurate wrist size.

In most cases, knowing your wrist size/length will be sufficient. Check your wrist size against the size of the strap that you wish to purchase on the individual product details page.

From there, you can select and purchase our watch straps: Small (S), Large (L) or Free Size.

2. What is the watch band width / watch lug measurement?


In certain cases, knowing your wrist size alone may not be sufficient. In such a scenario, you will need the watches' band width size, also know as the watch lug width size.

Your Apple watch will say the measurement on the back.

If you cant find the size on the back place the watch with the watch face facing up. Take the measurement of the distance between the lugs (where the watch strap fits).

For Apple Watches the you have the choice between 38MM, 40MM, 41MM, 42MM, 44MM, 45MM & 49MM, you can also enter your watch model number into a search engine to find what size your watch uses.

Apple Watch 7, 8, and 9: The Apple Watch Series 7, 8, and the newly released Series 9 are compatible with a wide range of our bands, including sizes 38MM, 40MM, 41MM, 42MM, 44MM, 45MM, and 49MM. For watch cases, they fit the 41MM and 45MM sizes.

Apple Watch Ultra and Ultra 2: The recently introduced Apple Watch Ultra and Ultra 2 are compatible with 45MM and 49MM bands. As for the watch cases, both the Ultra and Ultra 2 models are available in a 49MM size.

Using these three measurements, you are now ready to grab your band!

Questions? We've Got Answers! ⭐

Real talk about your new favorite watch band

Will this actually fit my watch?

Absolutely! Whether you’re rocking the original Series 1 or the latest model, we’ve got you covered. Just check the size on the back of your watch (if you're not sure), and we'll handle the rest. It’s that easy.

Are third-party Apple Watch Bands safe to use?

Yes. All Astra Straps use precision-machined stainless steel connectors that lock securely into your Apple Watch — the same mechanism Apple uses. They won't scratch your watch or interfere with sensors like heart rate or blood oxygen. All our materials are skin-safe and nickel-free, and using a Astra Straps band does not void your Apple Watch warranty.

What makes Astra Straps different?

Great question! At Astra Straps, we don’t just make bands – we craft them.

Every single band is hand-finished to ensure the highest quality and attention to detail. We’re all about combining top-notch materials with unique designs that reflect your personal style.

Plus, we test every band for comfort and durability, so you can count on a strap that’s as strong as it is stylish. When you choose Astra Straps, you’re not just getting a band – you’re getting a piece of wearable art.

What if I don’t love it?

We get it – sometimes things just don’t work out. If you’re not in love within 100 days, send it back, no questions asked. We’ll refund you, no drama. We want you to have a band you absolutely love.

When will it get here?

We’re all about speed. Most orders ship within 1-2 days, and you can expect it to arrive shortly after.

Plus, if you spend over $50, shipping is on us. Because let’s be real, no one wants to pay extra for shipping.

Is it really comfortable, or just good-looking?

Why settle for one when you can have both? Our bands are designed to look amazing and feel just as great.

We’ve obsessed over comfort, so you don’t have to. No weird pinching or “I need to take this off” moments – just a band that feels as good as it looks.

Will it stand up to my crazy life?

We’ve put our bands through the wringer because we know you don’t have time to baby your watch.

Whether you're hitting the gym, caught in the rain, or dealing with your most accident-prone friend, these bands are built to last. Bring on the hustle!

How do I pick the right size?

Most people use a tape measure (or even just a string) to wrap around their wrist, then add half an inch. But don’t stress – most of our bands are super adjustable, so unless your wrists are tiny or extra large, the standard size should work just fine. Still not sure? Reach out to us, we’re here to help!

Do I need to buy anything else?

Nope! We believe in keeping things simple. Everything you need is in the box. No sneaky extra fees or “must-have” connectors. Just open it, snap it on, and you’re good to go.

How do I keep it looking fresh?

Super easy! Silicone bands just need a quick rinse with soap and water. Leather ones? Just a gentle wipe down.

Metal ones can be cleaned with a soft cloth. And don’t worry – we’ll send you a full care guide, but these bands are pretty low maintenance.

Cute AND comfortable ?? I got the pale pink and have worn it almost every day since it arrived. Really happy with the color.

Really Nice Buckle

The buckle feels sturdy and is easy to fasten without fighting with it. Definitely prefer this style over some of the more complicated clasps.

Looks Great With My Watch

Looks great paired with the silver watch body. The little metal accents make everything feel coordinated rather than like a random replacement strap.

K
Kyle R.
Perfect for Everyday Wear

I've been wearing this to work, on walks and just around the house. It's one of those bands that works for pretty much anything.

Feels Secure on My Wrist

I like a band that I can tighten securely when I'm active and this works well for that. Buckle stays closed and the strap doesn't slide around.

Already Want Another Color

Okay I definitely didn't need another watch band...but now I want another color ?? The first one has been that good.

The Metal Details Make It

For me it's the metal details that make this one stand out. The connector and buckle give a basic silicone band a much more finished look.

Great Color Selection

There are so many colors I had trouble deciding lol. Started with navy but I'm thinking about getting the cream or green next.

Soft and Flexible

Silicone is flexible without feeling flimsy. It bends around my wrist comfortably and doesn't have that stiff plastic feeling.

Orange Really Stands Out

The orange version completely changes the look of my watch. Definitely gets noticed, which is exactly why I picked that color.

B
Bennett C.
Perfect Fit ??

Fit was spot on for my watch and installation was straightforward. Took barely any time to swap out my old band ??

S
Seth R.
Nice Balance of Sporty and Clean

I like that it has a sporty design without looking like something I'd only wear at the gym. I've worn it to work plenty of times.

My Favorite Band So Far

I've rotated through a bunch of bands and this one keeps ending up back on my watch ?? Comfortable and just looks right.

Black Is Clean and Simple

Can't really go wrong with black. Looks clean, matches basically everything I wear, and the metal accents keep it from looking boring.

C
Clayton D.
Good Looking Sport Band

If you like sporty watch bands this is a good one. Has a rugged design but still looks clean enough for normal daily wear.

R
Russell K.

Was pleasantly surprised when this arrived. Everything feels nicely put together and the hardware doesn't feel flimsy.

Stays Secure While Moving

I've worn it running and doing yard work and the buckle has stayed secure. Haven't had to stop and readjust it once.

Mint Green Looks So Fresh

Mint green was a little outside my normal choices but I'm glad I tried it. Such a fresh color, especially for spring and summer.

M
Mitchell F.
Easy to Adjust

Very easy to adjust because there are plenty of holes along the band. I can get it snug for exercise and slightly looser for regular wear.

R
Rhett J.
Looks Premium on the Wrist

The pictures made it look nice but I think it looks even better on the wrist. The metal pieces really elevate the design.

D
Dominic P.
Great for Workouts

Used this through two gym sessions already and it stayed put the whole time. Quick wipe afterward and it was good to go ??

N

The Pink Is Really Nice

Bought the soft pink one for my wife and she loves it. The shade is subtle and looks really pretty with her watch.

K
Kelsey M.
Exactly What I Wanted

Pretty much exactly what I was hoping for. Sporty silicone, proper buckle and enough adjustment holes to get the fit right.

E
Emmett R.
Comfortable Even After Hours

Had it on for most of the day and didn't get that annoying urge to loosen or remove it. Comfortable band overall.

Q
Quentin H.
Love the Metal Connectors

Those metal connectors are such a nice touch. They match the watch hardware really well and make the band look more expensive IMO.

G

Navy Looks Fantastic

The navy color is excellent. It's dark and understated but still gives the watch a little more personality than plain black.

R
Reid C.
Secure Fit All Day

Once the buckle is fastened it isn't going anywhere. I've used it walking, working out and doing stuff around the house with no issues.

T
Tanner B.
Nice Upgrade From the Original

Wanted something with a little more character than the original band and this did the trick. Makes the watch look completely different.

Great Everyday Strap

This has basically become my everyday strap. Easy to put on in the morning and comfortable enough that I forget I'm wearing it.

M

Looks Better in Person

Honestly looks better once you put it on. The metal hardware and silicone combination gives it a much nicer appearance than I expected.

K
Kendall S.
Really Comfortable Band

Wore this for an entire day including a workout and it stayed comfortable. The silicone has enough flexibility that it moves naturally with my wrist.
