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.
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.
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 the 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!

This elastic strap is high quality and easy to adjust. The spring connections could be a bit tighter, but for the price and overall comfort, its a great strap.
I have a small wrist, and this strap fits perfectly. It also washes well without retaining odors and is easy to adjust.
This strap is perfect for my active lifestyle. Its lightweight and adjustable, making it great for workouts and daily wear. It stays in place without being too tight and even works well with wrist wraps. Exactly what I needed!
It took a little longer than expected to install, but once I got it right, it was a perfect fit. The strap is comfortable, and Im satisfied with it.
Super comfortable strap! I prefer these over the rubber ones because of my sensitive skin. Theyre also much easier to put on and are very durable.
I was looking for a replacement strap for my metal one, and this nylon strap is exactly what I needed. Its lightweight, easy to adjust, and doesnt catch on clothing. Very happy with it.
I bought several straps, and this one is the best. Its stretchy, stylish, and doesnt irritate my sensitive skin. It also didnt stretch out after daily use and doesnt absorb odors. Overall, its a great strap.
Im very sensitive to wearing watches, so I was looking for something lightweight for my Galaxy Watch Ultra. This strap fits perfectly and is so comfortable I ordered more. Highly recommend!
This strap is really comfortable and doesnt irritate my skin. Just be careful not to wash it with the pins attached, as they can fall out. Otherwise, its a great band!
Works great with my Galaxy Watch Ultra. Comfortable and easy to wear.
The watch straps that came with my smartwatch didnt fit right, but this one is much better. Its comfortable and easy to adjust, which helps my Galaxy Watch Ultra track my health data more accurately. Definitely recommend it!
I wasnt a fan of the original strap that came with my Galaxy Watch Ultra. After it broke, I replaced it with this one, which is much more comfortable. Highly recommend!
I wanted something lightweight that I wouldnt notice while wearing, and this is it! Very comfortable and light. Ill be buying more colors.
This is the best stretchy nylon strap Ive found for my small wrists. It stretches just enough to go over my hand and stays secure without needing constant adjustment. The colors are also really nice!
So much better than the leather strap that came with my Galaxy Watch. Its snug but comfortable, and now I wear my watch all the time.
Arrived quickly and fits perfectly on my watch. Love how easy it was to install.
“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."
“Don't waste money on expensive Apple bands. This one is stylish, fits well, and is excellently made. You can get several of these for the price of one official band."
“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."
