Two sizes dominate the Birkin conversation: the compact Birkin 25 and the classic Birkin 30. Choosing between them comes down to three questions — how much will you carry, how often will you use it, and how much premium will you pay to own the harder-to-find size?
Live 2026 Resale Prices
Pulled live from our inventory across Fashionphile, Rebag, FARFETCH, The RealReal, 1stDibs, StockX, Vestiaire Collective, and eBay:
- Birkin 25 — 117 bags live, average $30,391, range $16,610 – $289,000
- Birkin 30 — 200 bags live, average $23,097, range $11,710 – $106,845
The Birkin 25 carries a ~32% premium over the Birkin 30 on the resale market, driven by scarcity and evening-to-day versatility. Hermès produces fewer Birkin 25s than 30s, and most of them are quietly absorbed by VIP clients before hitting the open market.

Which Size is a Better Investment?
Different sizes can have different asking prices, but a cross-sectional price gap is not an investment return. Use our same-listing index to follow median asking-price changes, and compare condition and specifications before buying. It does not establish which size will appreciate faster or sell sooner.
Which Should You Buy?
- Pick the 25 if: you carry a minimalist kit, you love statement pieces, you're under 5'6", or you already own a larger daily bag.
- Pick the 30 if: you want one Birkin for everything, you're budget-conscious (save ~$7,000 on average), or you travel frequently.
