Size guide

At Astra Straps, all our straps have specific and clear 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.

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

With these two pieces of measurements, you are now ready to grab your strap!

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.

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.

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!

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 £40, shipping is on us. Because let’s be real, no one wants to pay extra for shipping.

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.

Staying on My Watch

I've swapped straps way too many times trying to find the right one for my Ultra. Think this one is staying on for a while. Comfortable + secure = done.

F
FloraM_413
Great colour Selection

There are way more colours than I expected. I almost bought black but went with the darker blue instead and I'm glad I did. Looks sharp.

D
Dulcie Arkwright
Exactly What I Needed

Needed something that could handle the gym without looking like an ugly workout-only strap. This does both. Sporty but still nice enough for daily wear.

H
Hester Bellwood
Handles Sweat Easily

Did a sweaty outdoor workout in this and it handled it fine. Didn't absorb anything and there was no funky smell afterward ??

E
ElizaK_657
Bought a Second colour

Started with grey and came back for the navy one. I usually don't buy multiples of the same strap but I liked the fit enough to want another colour.

C
Cecily Norwood
Simple but Really Good

No complicated clasp, weird mechanism or anything. Just a good buckle, plenty of holes and comfortable silicone. Sometimes simple is better.

M
MinnieB_239
My New Weekend strap

This has basically become my weekend/outdoor strap. I put it on Friday and usually don't swap it back until Monday ?? comfy and easy to clean.

F
Fleur Ramsden
Breathable and Secure

The combination of the holes and silicone material works well for exercise. Still gets sweaty obviously, but nowhere near as uncomfortable as my solid strap.

E
Etta Willoughby
Looks Great With the Ultra

It looks like it was designed for a rugged watch instead of just being a generic silicone strap. Really suits the Galaxy Ultra.

H
HettieUK_824
Perfect Hiking strap

Bought this specifically for hiking because I didn't want to keep sweating through my nicer strap. Turns out I like this one enough that I'm wearing it during the week too.

N
Nellie Forrester
Good Fit on My Wrist

Lots of adjustment points so getting the fit right wasn't an issue. I can wear it snug for running and loosen it a little afterward.

D
DulcieM_571
Doesn't Feel Stiff

Some silicone straps feel like stiff rubber when they're new. This one bends naturally around my wrist right away, which I appreciate.

M
Mabel Gresham
Orange Was the Right Choice

Orange gang ?? Seriously this colour completely changes the look of the watch. I've already gotten two comments on it at the gym.

A
Ailsa Redmayne
Easy to Wash Off

One reason I prefer silicone for workouts is how easy it is to clean. Sweat, dirt, sunscreen...quick wash and it's back to normal.

P
PosyJ_346
Love the Sporty Design

The double rows of holes give it a proper sport watch vibe. Looks especially good with the larger Galaxy watch face IMO.

E
Etta Marsden
Comfortable for Hours

Had this on from about 7am until late evening yesterday. No rubbing or weird pressure points. Pretty comfortable considering how big the Ultra itself is.

F
FloraK_918
Great Outdoor Strap

Used mine during a weekend hike and got it dusty, sweaty and a little wet. Rinsed it under the faucet when I got home and it cleaned right up.

M
Minnie Elwood
Didn't Expect to Like It This Much

Was expecting another average silicone strap tbh. This one surprised me. The ventilation makes more difference than I thought and it feels good on my wrist.

C
Cora Blackshaw
Gym Tested ??

Workout approved ?? Did weights followed by 30 mins on the treadmill and the strap stayed put. Quick rinse afterward and it was good again.

T
TillyMae_693
Solid Everyday strap

I've been wearing this to work, the gym and around the house. Nothing fancy to say...it just works and it's comfortable. That's honestly what I wanted.

O
Ottoline Mercer
Really Like the Grey

Went with grey because I wanted something neutral but not boring black. Really clean looking in person and matches pretty much everything I wear.

N
NellW_257
Fits Like It Should

Snapped onto the watch without any fighting or forcing. Fit feels secure and I've had zero issues with the connection since installing it.

E
Eliza Wetherby
Much Better for Sweaty Days

If you live somewhere hot, the ventilation alone makes this worth trying. My old solid silicone strap would get gross underneath after an hour outside.

H
Hester Langton
Nice Secure Buckle

I'm picky about buckles because I've had cheap ones come loose before. This one has stayed secure so far even when I'm moving around a lot.

E
EdieUK_864
Army Green Is My Favorite

Army green looks sooo good with the Galaxy Ultra. Been wearing mine hiking and doing yard work and it fits that outdoorsy look perfectly.

F
Flora Denham
Great for Running

Took it on my morning run and completely forgot about it, which is exactly what I want from a watch strap. No sliding and no stopping to readjust.

C
CecilyM_319
Looks Tough on the Wrist

This makes the watch look even more rugged IMO. I got black and it has a clean tactical-ish look without being too over the top.

M
Martha Penrose
The Holes Actually Help

At first I figured all those holes were mostly part of the design. Nope ?? they actually make the strap noticeably more breathable during workouts.

A
Ailsa Broughton
Super Comfortable

The silicone has a nice amount of flexibility to it. Not super floppy, not stiff either. I've worn it basically all day several times without wanting it off.

N
NellieK_705
Finally a Good Workout strap

Finally found a strap I actually like wearing at the gym. Secure enough for lifting and cardio, but I don't get that sweaty trapped feeling underneath afterward.

G
Georgie Ransome
Perfect for My Galaxy Ultra

Fits my Galaxy Watch Ultra really nicely. The ends sit where they're supposed to and there's no annoying wiggle around the connection. Very happy with it.

M
MabelJ_482
Orange Looks Insane ??

Went straight for orange ?? It's bright, loud and looks awesome with the dark watch. If you're trying to be subtle maybe don't get orange lol, but I love it.
