Size guide
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?
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.
Customers praised this seamless sport loop as "durable and flexible" with exceptional comfort. The buckle-free design slides on easily and "feels like I'm not wearing a watch band at all." Ideal for workouts and small wrists. However, some noted sizing runs slightly large for petite wrists. Highly affordable alternative to premium brands with great color variety.

Bit thinner than the original apple band but I've worrn it for about 2-4 weeks now and it is proving to be very durable. I love this color and it stands out nicely without being too bold. I am assuming that this feedback will be attached to a picture of the band I biought - burgundy sport loop band
B
Just perfect
M
Quality is excellent
M
Very good product and really fits well on the wrist

S
Really comfortable, taken in 4 colors and all look with the clock.
A
Its so cute!!!
V
Durable and flexible, comfortable band, not tight like most bands made from similar material. Very well fitted. Love that its one seamless piece, no buckle digging into my wrist during a run. Connector's held up great too, never had it come loose mid exercise 😊
S
Was lovely, but a little too small for me honestly. No problem sending it back tho. Stayed put really well while i had it on, didnt slip at all during my workouts 👍
M
Good band for the price, it was the smallest size i could find. Nice color selection too, went with one that matches my usual gym stuff.
J
Love the pink color. However the small size is a bit too big for my wrist. Kept it anyway becasue of the color, wear it high up on my wrist. Might have to look at getting a smaller size elsewhere. Its lightweight enough that i forget its even on my wrist by midday.
L
Has a nice snug feel without being tight
L
I like how simple it looks, nothing sticking out or getting in the way. Just clean and easy
O
Feels proper light, doesn't weigh the wrist down even after a long day
G
Easy to chuck on, no fiddly bits at all
S
Been using it most days and it just blends in with everything I wear
J
Excelent fit and comfortable
R
Love my apple watch loop band. Fits perfectly around my small wrist, nice color and strong. Shipping to NZ was fast too.
R
Exactly what I was after - just like the one that came with my watch. Recommend!
L
I have been on the hunt for a good infinity watch band. This is silicone, so perfect if you work out/sweat. Easy to change, slide on and off, so it looks very sleek and have that expensive vibe, but the price is unbeatable! 10/10!
L
This is one of the most comfortable bands Ive ever purchased. Super easy to take on and off, great fit, and very comfortable to wear all day.
M
This band is not perfect, but it's great value for what you get.
R
This watch band fits perfectly! The band was stretchy enough to put on, but once on, it tightened perfectly around my wrist. I love the less bulky style, and the price was great.
A
This watch band is so comfortable! I ordered a small, and it was definitely true to size. I love the colors and the stretch of this band.
B
Love my new watch band. Its so soft and very comfortable. Easy to get on and off. Love the value! Will get more colors!
J
Simple to assemble and put on daily. I ordered a small. Fits great!
K
Very comfortable and nice looking.
J
I am happy with my purchase. It's easy to put on, take off, and switch to different color bands. The color is just as I expected. If I decide that I want different colors, I will be purchasing again!
