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.

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 measurement data points, 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.

And the best part? Shipping is free—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.

Magnet holds nicely!

The magnetic closure feels secure and the silicone is comfortable on my wrist. Really like how simple it is to adjust.

WOW... so easy to wear!!!

No more fiddling with tiny buckles before work. Just wrap it around and I'm ready to go. Love this design!

Comfortable for daily use

The silicone feels smooth and doesn't dig into my wrist. I've been wearing this style throughout the day without much fuss.

Really nice magnetic band

The magnetic fastening is convenient, although I sometimes need to readjust it after a busy day. Still a good watch band.

J
Jade Despins
Looks great on my Galaxy Watch

The black band gives my Galaxy Watch a clean, modern appearance. It looks good with both casual and office clothes.

Émile Lussier
No buckle marks anymore!!!

I love being able to choose exactly how snug I want the band. The magnetic adjustment is so much easier than traditional holes.

Such a clever design

The overlapping silicone ends are a nice touch. It sits neatly around my wrist and doesn't have a loose tail sticking out.

R
Rowan Beckett
Soft silicone, good fit

The band feels comfortable and flexible. I wish the magnetic section was a little longer, but overall I'm pleased with the design.

T
Tessa G.
WOAH this is convenient!

I didn't expect a magnetic band to be this easy to put on. It takes seconds and looks really sleek!!!

M
Mathis Bérubé
Perfect minimalist style

I wanted something simple without a bulky clasp. This magnetic silicone band is exactly the kind of design I was looking for.

L
Leah McCready
Great for office days

The smooth black finish looks surprisingly smart. I like having a sporty material without the usual chunky sports-band appearance.

Adjusts without any holes

Finally, a watch band that doesn't force me to choose between two buckle holes! I can get a much more precise fit.

M
Mélina Savard
Nice band for workouts

The silicone is easy to wipe down after exercise. I do check the magnetic overlap before running, but it's comfortable for everyday activity.

The orange detail is awesome!!!

I love the black and orange combination. The orange underside gives it a fun pop of colour without being too flashy.

C
Chantal Mercier
Easy to put on one-handed

This is so much easier than fastening a normal buckle. I can adjust it quickly with one hand, which is a big plus.

c

Feels smooth against my skin

The soft silicone is the best part for me. No rough edges or stiff buckle pressing against my wrist.

D
Daphne McNeil
A good everyday replacement

I replaced my older watch band with this one. The magnetic closure is handy, though it takes a little practice to position evenly.

A
Alexis Moreau
Love the clean finish

The band has a really neat appearance once wrapped around the wrist. It makes my Galaxy Watch look more streamlined.

j

Seriously comfortable!!!

WOW! I love how flexible the silicone feels. The band follows my wrist nicely instead of feeling stiff and bulky.

Great neutral colour

I chose the grey option because I wanted something understated. It pairs beautifully with the silver watch body.

N

Magnetic closure is a winner

The magnetic design is so practical for quick adjustments. I like being able to loosen it slightly during a long day.

M
Maude Bélanger
Good but takes some adjusting

The material feels nice and the band looks stylish. Getting the overlap perfectly aligned takes me an extra moment.

e
eric_tor
Perfect for smaller wrists

I always struggle with bands that leave a long extra piece hanging out. The wraparound design looks much tidier.

B
Brenna Walsh
The black one looks amazing

Simple, sleek, and goes with everything. I love that there isn't a metal buckle interrupting the look.

O
Olivier Caron
Really handy for everyday wear

I can loosen the band quickly when my wrist feels warm and tighten it again without removing my watch.

k

Nice alternative to a buckle

The magnetic fastening is convenient and the silicone has a pleasant texture. I still prefer a regular buckle for intense sports.

J
Jérémie Leduc
My favorite band style!!!

I've tried several different watch band styles and this magnetic loop is one of the easiest to wear. Such a smart idea!

S

The black silicone has a clean sporty look. It works nicely with my workout clothes and everyday outfits.

D

No annoying band tail

One thing I really like is how the end overlaps neatly. No extra silicone sticking out and catching on my sleeves.

m

Comfortable around the wrist

The band bends naturally and feels pleasant against my skin. The magnetic hold is fine for my normal daily routine.

C
Cora McBride
Looks more expensive than expected

The simple design gives the watch a polished look. The smooth finish and hidden-style closure are really appealing.

E
Evan P.
WOW the fit is adjustable!!!

Being able to fine-tune the fit without buckle holes is amazing. My watch finally sits where I want it!

Naomie Allard
Great with my silver watch

The contrast between the silver watch case and black silicone band looks fantastic. Very modern and understated.
