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.

  • “I recently got the Astra Apple Watch band and am very impressed with its quality and stunning design. Right from the packaging, it was clear this band was made with great care. The premium-grade silicone is soft against the skin, comfortable for all day wear, and durable enough for an active lifestyle. Im thrilled with my purchase."

  • “Ive had many Apple watch bands over the years, and this is the best, coolest, and most comfortable one yet. It makes the watch look extremely upscale. A friend paid much more for the same band elsewhere and couldn't believe my price. Highly recommended. Love!"

  • “Amazing quality, very flexible and not stiff like other straps. Doesn't have that cheap band smell. Highly recommend, and great to have the option to match the strap color with my style."

  • “I was looking for a band thats not only exceptionally comfy but also stylish and durable. These bands tick all those boxes. I appreciate the bands design where it tucks in neatly. My original band caught on everything, but this one has a much smoother design. I love it!"

  • “Astra Straps' customer service is top-notch. I had a question about sizing, and they responded promptly with helpful guidance. It's refreshing to see a company that values its customers."

  • “Astra Straps has been a game-changer for my watch collection! Their bands are not only stylish but incredibly durable. I've swapped out all my old bands for Astra and couldn't be happier."

  • “The watch bands fit perfectly around my wrist as there are plenty of holes to adjust to my wrist size. The colors are very nice. The feel of the band is smooth. The way the band clasps is a plus as it is very secure on my wrist."
