A guide to Hermès Birkin sizes — the 25, 30 and 35 compared on look, practicality and resale value — to help you choose the right one to buy and keep.
The Birkin comes in several sizes, but the 25, 30 and 35 are the mainstays — and the one you choose changes both how the bag wears and how it holds its value. Here is how they compare.
The Birkin 25
The most in-demand and the hardest to find — a jewel-like day bag that carries the strongest resale premium of the three, often well above retail. The trade-off is capacity: it holds the essentials and little more.
The Birkin 30
The classic all-rounder and, for many, the 'just right' size. It takes a day's essentials comfortably, wears with everything, and enjoys the deepest liquidity on the secondary market. If you want one Birkin to do everything, this is it.
The Birkin 35
The original size — roomy, more of a work or travel bag. Demand has softened in recent years in favour of the smaller sizes, which often makes the 35 the best value of the three if the capacity suits you.
Which holds value best?
- 25: highest demand and premium, the strongest store of value, the least practical.
- 30: the best balance of wearability and resale — the safe all-round choice.
- 35: the most practical and roomy, the gentlest on the wallet, with softer resale.
For a first Birkin to keep, a neutral 25 or 30 in Togo or Epsom is the market's evergreen. Tell us the size and specification you are after and we will source it, authenticated beyond question.
Frequently asked questions

Which Birkin size holds its value best?
The 25 typically holds value best thanks to the strongest demand, followed closely by the 30. The 35 is more practical but has softer resale, which can make it better value to buy.
