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?
Since 2020, the Birkin 25 has appreciated faster than the 30 on every resale marketplace — the gap has widened from roughly 15% to over 30%. But liquidity matters: the 30 is easier to resell quickly because there are more buyers at any given price point. If you're buying to flip, the 25 offers more upside. If you're buying to wear and may liquidate later, the 30 trades faster.
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.
