A Clear Guide to Fit & Proportion

Choosing the right size is part of a confident purchase. The guide below is designed to help you better understand measurements across bags, jewellery, watches, sunglasses, and wallets, so each piece feels right for your style and everyday use.

Bags +

How to check size

Bags are usually listed as Width × Height × Depth.

  • Width: horizontal space
  • Height: how tall the bag is
  • Depth: how much it can hold
  • Strap drop: how it sits on the shoulder or in the hand

Before ordering

  • Compare the dimensions with a bag you already use.
  • Check that your phone, wallet, sunglasses, and essentials will fit.
  • If you use a long wallet, check the width carefully.
  • If you want shoulder wear, check the strap drop.
Jewellery +

Rings

  • Measure the finger where the ring will be worn.
  • You can also measure the inside diameter of a ring that fits well.
  • If you are between sizes, the larger size is usually safer.
