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.

Would Definitely Get Another

Would buy again. I especially like the stretch because my wrist seems to change size depending on heat/workouts and this doesn't start feeling annoyingly tight halfway through the day.

D
Deacon S.
Orange Was the Right Choice

I almost ordered black like I always do but went orange instead. Glad I did!! It's fun without looking ridiculous and makes my watch stand out a little more. ??

Stays Where I Put It

I've been wearing mine during tennis and it doesn't shift around even with all the wrist movement. The hook-and-loop closure has stayed secure every time so far.

K
Kellan P.
Simple but Really Good

Sometimes the simplest accessories end up being the ones you use most. That's basically this band for me. Comfortable, adjustable and easy to match with everything.

B
Brett F.
My Wrist Can Finally Breathe

My wrist gets hot really easily under watch bands. This design seems to let more air move through and I've noticed a difference. Not glamorous lol, but very useful.

S
Sutton J.
Surprisingly Nice Quality

Honestly nicer than I thought it would be. The material has a good amount of stretch and the attachment feels secure. Took maybe 10 seconds to get it onto my watch.

T
Teagan V.
Good Band for Running

Used this during several runs now and it's held up great. I especially like being able to fine tune the tightness before I start so the watch sensor stays against my wrist.

A
Alden M.
Actually Comfortable All Day

Had it on from about 7am until after dinner yesterday and never had that "get this thing off my wrist" feeling. ?? That's a win because I'm usually picky about bands.

Q
Quincy B.
The Black One Looks Clean

Black was definitely the right pick for me. Looks clean enough for work but still sporty. I've worn it with gym clothes and regular office stuff and it doesn't look out of place.

H
Hollis K.
Nice for Hot Weather

Really nice for hot days. I work outside part of the week and my old silicone strap would get uncomfortable by lunchtime. The woven nylon feels much more breathable.

M
Maren D.
Exactly What I Needed

This is one of those purchases where there's not much to complain about. Fits well, feels good and hasn't opened accidentally. Been wearing mine almost every day.

J
Jensen R.
Secure Without Being Tight

I like my watch fairly snug during runs and looser the rest of the day. This makes that super easy because you're not limited to preset holes. Just adjust it wherever it feels right.

E
Ellis T.
Much Better Than My Old Band

My previous sport band was comfortable until I started sweating. This one handles workouts much better for me. It also feels noticeably lighter on the wrist.

B
Bryant C.
Love the Ribbed Design

The raised stripe pattern is a cool detail. It's subtle on black but gives the band some texture so it doesn't just look like a flat piece of fabric.

R
Reid H.
Solid Workout Band

I've used it for strength training about 4 times now. Doesn't slide around when I'm lifting and I can make it snug without making my wrist feel squeezed.

C
Callan W.
Easy On and Off

Being able to rip it open and put it back on quickly is honestly one of my favorite things about it. Great when I'm constantly taking my watch off to charge or shower.

D
Davis P.
Really Comfortable Nylon

The nylon feels nicer than I expected. It's flexible rather than stiff and the striped texture gives it a little more character than the plain fabric loops I've owned.

S
Shea M.
Survived a Very Sweaty Weekend ??

Wore this hiking on a humid weekend and it got absolutely put through it lol. Sweat, sunscreen, dirt, everything. Cleaned it afterward and it's still going strong.

L
Lennox J.
Great for Smaller Wrists

My wrists are on the smaller side and buckle bands usually leave a long tail sticking out. This adjusts much better for me and doesn't have all that extra material flapping around.

C
Clifton R.
Bought Another Color Already

Bought the gray first and liked it enough that I came back for another color. That almost never happens with watch bands for me, so yeah...pretty happy with it.

G
Greer N.
Goodbye Sweaty Silicone

If you hate that sweaty patch you get under silicone bands, try this style. I'm not saying your wrist magically won't sweat ?? but it feels WAY less stuffy during workouts.

H
Holden B.
Nice Stretch Without Feeling Loose

There's a nice amount of give in the nylon. It stretches when I flex my wrist but doesn't feel floppy or loose. Good balance.

T
Tatum F.
Barely Notice It on My Wrist

I forgot I had my watch on while reading on the couch, which sounds weird but that's basically the best compliment I can give a watch band lol. Very comfortable.

B
Brennan D.
Perfect for the Gym

Gym bag essential now. Seriously. It's lightweight, doesn't pinch, and I can tighten it exactly where I want instead of choosing between two buckle holes.

M
Marlo K.
Hook and Loop Holds Really Well

I was a little skeptical about the hook and loop holding through workouts but so far it's been rock solid. I've done weights, rowing and a couple runs with zero issues.

T
Tobin S.
My New Everyday Band

Started out using this just for workouts but now I leave it on most days. Comfortable enough at my desk and still works when I head straight to the gym after work.

C
Camden V.
Simple and Actually Works

Nothing fancy here and that's kinda why I like it. Easy to put on, easy to adjust and it stays secure. Exactly what I wanted for an everyday watch band.

R
Roscoe H.
Comfortable Even When Sweaty

I sweat like crazy during cardio and this has been much more comfortable than my regular silicone band. It doesn't get that sticky feeling underneath. Huge improvement for me.

D
Della P.
The Orange Looks Awesome

Got the orange and it's BRIGHT in the best way. Makes my watch look way more sporty. I've already had somebody at the gym ask me where the band came from.

W
Wesley T.
Did Not Expect to Like It This Much

Wasn't expecting much because I mainly bought it as a spare gym band. Welllll now I'm wearing it more than my expensive one ?? It's soft, stretchy and doesn't feel bulky at all.

K
Keaton M.
Stayed Put During My Run

Took it on a 5 mile run and was expecting to readjust it at some point...nope. Stayed exactly where I put it. It got sweaty obviously but never felt gross or slippery.
