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!

“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!"
-

-
“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 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."
