Hermès Kelly Size Guide: 20 vs 25 vs 28 vs 32
Four sizes, four very different lifestyles — a practical breakdown of capacity, wearability and who each size actually suits.
Choosing the right Kelly size matters more than almost any other decision in the buying process — the wrong proportions can leave an otherwise perfect bag sitting unused in a closet. Hermès offers the Kelly across four primary sizes, each genuinely suited to a different daily routine rather than simply scaling the same bag up or down.
This guide breaks down 20cm, 25cm, 28cm and 32cm individually by capacity and wearability, then compares them side by side so you can match the size to your actual lifestyle.
Kelly 20: The Mini
The Kelly 20, often called the Mini Kelly, is a genuinely compact size best suited to evening use or carrying only the most essential items — a phone, cards and lipstick, roughly. It's a striking, statement-making size, but not a realistic daily workhorse for most buyers with typical daily-carry needs.
Kelly 25: The Compact Everyday
The Kelly 25 steps up meaningfully in capacity while retaining a compact, elegant profile. It suits buyers with lighter daily-carry needs or those who prefer a smaller silhouette on a petite frame, though it can feel tight for anyone who needs to carry a larger wallet or additional items regularly.
The right Kelly size isn't the one that looks best on someone else — it's the one that still feels right after carrying it all day.
Kelly 28: The Sweet Spot
The Kelly 28 is widely considered the most versatile, practical size in the lineup, comfortably fitting a wallet, phone, sunglasses case and small cosmetics pouch without feeling overstuffed. It works well across a broad range of body types and daily routines, which is precisely why it's so frequently recommended as a first Kelly purchase.
Kelly 32: The Capacity Choice
The Kelly 32 offers substantially more room, suited to buyers who need to carry a tablet, larger organiser, or simply more daily items than the 28 comfortably allows. It also tends to suit taller frames particularly well, where its larger proportions read as balanced rather than oversized.
Try before committing when possible
Because Kelly proportions interact so directly with body frame and daily habits, trying different sizes in person — even if the exact leather or colour isn't available — is genuinely worth the effort before finalising a size decision.
Full Size Comparison
| Size | Best For | Capacity |
|---|---|---|
| 20cm | Evening / minimal essentials | Very Small |
| 25cm | Light daily carry | Small |
| 28cm | Everyday practical use | Medium |
| 32cm | Larger daily capacity | Large |
28cm Remains the Safest Starting Point
If you're unsure which size to choose, the Kelly 28 offers the broadest practical appeal across body types and daily routines. Buyers with very specific needs — evening-only use or genuinely heavy daily loads — are better served by the 20cm or 32cm respectively.
When in doubt, size up rather than down — an underused bag is a more common regret than an oversized one.
