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!

White silicone band
I had a white band I purchased from Apple years ago and it got torn and I was no longer able to wear it. I have been looking for months for a replacement and found this one. I am very happy with the quality and fit of this band and extremely happy with the price. I am considering purchasing the same band in other colours.

Loop Band
I ordered the loop band because of its looks. Unfortunately, it was too large and I worked with the customer service to help me out. Their service was impeccable and I wouldn't think twice to order another Astral product.

i 12-06-2025Perfect Apple band replacement
I found this while searching for replacement Apple Watch bands in Canada. My original Apple Watch band from Apple that was an orange colour began to rip, so I needed a replacement. Unfortunately, Apple doesn’t seem to offer the colour anymore, at least in this specific style. Luckily, this company offers quite a lot of colours, one of which is “kumquant” (fancy for orange). I actually like their colour more than Apple’s, which was more on the pinker side than true orange. I wear a size 4 from Apple and got the small from this company. It’s a perfect fit. Quality is the same as Apple, maybe even softer. I’m very pleased with my purchase and would shop here again. Attached photo shows the comparison of the colour (Astra is worn vs Apple laying next).
