The Birkin 25 and Birkin 30 are today's most sought-after sizes. Here is how to choose.
Capacity
The 25 holds a phone, wallet, keys, sunglasses and small essentials. The 30 adds room for a small tablet, a pouch or a scarf.
Proportions
The 25 looks elegant and jewel-like, especially on petite frames. The 30 is balanced and suits most heights.
Everyday use
If this is your only Birkin, the 30 is often more practical. If you carry little or already own a larger bag, the 25 is a joy.
Leather matters
A 30 in Togo slouches slightly; a 25 in Epsom stays crisp. See our leather guide.
