Sizing and answers to the questions we get most.
Size guide
Measurements are listed on each product page. Use the references below to work out your size before you order — since items are final sale, it’s worth a minute up front.
Rings (US sizes)
Wrap a strip of paper around the base of your finger, mark where it meets, and measure the length in millimetres against the circumference column.
| US size | Inside diameter (mm) | Circumference (mm) |
|---|---|---|
| 5 | 15.7 | 49.3 |
| 6 | 16.5 | 51.9 |
| 7 | 17.3 | 54.4 |
| 8 | 18.1 | 57.0 |
| 9 | 18.9 | 59.5 |
| 10 | 19.8 | 62.1 |
| 11 | 20.6 | 64.6 |
| 12 | 21.4 | 67.2 |
Watches
Case size is listed in millimetres on each watch. As a rough guide: 34–38mm reads smaller and sits neat on most wrists; 40–42mm is a middle, everyday size; 44mm and up reads large. Strap length fits most adult wrists; where a watch has removable links, that’s noted on its page.
Bracelets
Measure around your wrist just below the wrist bone with a strip of paper, then add about 1.5–2cm for a comfortable fit. Each bracelet’s length is on its product page.
Chains and necklaces
Necklace lengths are listed on each product page. As a reference: 40–45cm sits at the collarbone, 50cm sits just below, and 55–60cm sits lower on the chest.
Phone cases
Choose your exact model on the product page — an iPhone 15 case will not fit an iPhone 15 Pro, and Plus/Pro Max sizes differ again. If you’re unsure of your model, check Settings → General → About on the phone.
FAQ
When will my order arrive?
Every order is tracked, and you’ll get an email with tracking once it ships. Delivery times vary by item; you’ll always have a tracking number to follow your parcel from your order page.
How do I track my order?
Use the tracking link in your shipping email, or the “Track your order” link in the footer. You don’t need an account to track.
Can I return something if I change my mind?
We don’t accept change-of-mind returns — everything is final sale. Please check sizing and, for cases, your exact phone model before ordering. If an item arrives damaged, faulty, or isn’t what you ordered, we’ll replace it or refund it; see our refund policy.
What if my item arrives damaged or faulty?
Email support@east20th.com within 14 days of delivery with your order number and a clear photo. Once we’ve reviewed it we’ll send a replacement or refund you in full — you won’t need to return the item.
Can I cancel or change my order?
Yes, if it hasn’t entered processing yet — usually within about 12 hours of ordering and always before you get a dispatch email. Message support@east20th.com with your order number as soon as you can.
What payment methods do you accept?
All major cards, plus Apple Pay, Google Pay and PayPal. Charges appear as EAST20TH on your statement.
How do I know a phone case fits my phone?
Pick your exact model on the product page. Each case design lists the models it fits. If your model isn’t listed, we don’t currently stock that case for your phone.
Is my payment secure?
Yes. Payments are processed by our payment providers over a secure connection, and we never see or store your full card details.
How do I contact you?
Email support@east20th.com and we’ll reply within one business day, Monday to Friday. Put your order number in the subject line and we’ll get to it faster.
