Hermès Kelly Sizes: Mini, Pochette, 20 cm, 25 cm, 28 cm, 32 cm, 35 cm, 40 cm & 50 cm Explained
By the Privé Porter Editorial Team · Hermès specialists since 2008
Hermès makes the Kelly in sizes from the 15cm micro to the 50cm travel Kelly, with the Kelly 25 and 28 the most requested today. The Mini Kelly II (the 20cm size, about 19cm wide, Sellier only) and the strapless Kelly Pochette are the small-bag icons. Privé Porter, the Miami Hermès specialist, sources every Kelly size.
Kelly sizes follow the same logic as the Birkin, the number is the width in centimeters, but the Kelly family is wider and more nuanced. It includes a crossbody mini, a strapless clutch, a briefcase and a true travel bag, and the choice between Sellier and Retourne construction changes how each size looks. This guide covers them all.
For the story of how the bag got its name and the broader timeline, read our Kelly history and sizes overview.

The small Kellys: Micro, Mini Kelly II and Pochette
What is the Mini Kelly II?
Hermès produced Mini Kellys from the 1980s in sizes from 20cm down to a 15cm micro, paused them in the mid-2000s, and relaunched the bag in 2016 as the Mini Kelly II with a slimmer handle and a thinner body made for crossbody wear. It is built Sellier only and measures roughly 19 x 11.5 x 5.7 cm (7.5" x 4.5" x 2.25"). A phone, cards, a key and a lipstick fit. It is currently the most requested small bag we source; we will cover its colors and leathers in a dedicated guide. A classic example in our collection is the Mini Kelly II in black Epsom with gold hardware.

Kelly Pochette vs Mini Kelly
The Kelly Pochette is the elongated clutch of the family, about 22 cm wide (8.5" to 8.7" wide, 5.1" to 5.5" high and 2.4" to 2.8" deep, roughly 22 x 13 x 6-7 cm), with a flat top handle and no shoulder strap or strap rings. It is carried in the hand or under the arm. We compare the two in detail in Kelly Pochette vs Mini Kelly.

Kelly To Go and Kelly Elan
Two newer pieces carry the Kelly name without following classic sizing. The Kelly To Go is a wallet-on-strap built around the Kelly closure. The Kelly Elan is a slim flap bag that keeps the turn-lock and sangles in a flatter profile. Both suit clients who want the Kelly look in the smallest possible footprint.
The core Kellys: 25, 28, 32 and 35

Kelly 25 vs 28: which size should you buy?
The Kelly 25 holds a compact wallet, phone, keys and sunglasses. The Kelly 28 adds roughly 3 cm of width and height, enough for a full-size wallet and a small pouch, and it is the size we recommend most often as a first Kelly. In our experience, the 25 and 28 are the most popular and practical sizes. If you wear your Kelly crossbody, the 25 sits more neatly at the hip; if you carry by hand, the 28 has better presence.
The Kelly 32: the original standard
The Kelly 32 was once the standard size. It is a refined work bag that fits documents and a small tablet. Vintage 32s in Box calf are among the most elegant entry points into Kelly collecting.
The Kelly 35
The 35 is the Kelly as a briefcase alternative: wide enough for files, still graceful in Retourne. Like the Birkin 35, it is less fashionable today, which can make it good value.
The travel Kellys: 40 and 50
The Kelly 40 is a weekend bag and a frequent choice for men. The Kelly 50 is luggage in all but name, with room for a change of clothes. Both appear on the market far less often than the core sizes, and we confirm construction and specification bag by bag.

Sellier vs Retourne by Kelly size
Sellier Kellys are stitched on the outside, giving sharp edges and a structured trapezoid; Retourne Kellys are stitched inside out and turned, giving a softer, rounded silhouette. The Mini Kelly II and Kelly Pochette are Sellier. The 25 through 35 are made in both. Sellier suits firm leathers like Epsom and Box; Retourne flatters supple Togo, Clemence and Swift, as on this Kelly 25 Retourne in white Swift. Read our guide to choosing Sellier or Retourne for more.
The classic Kelly pairs a single top handle with a detachable shoulder strap, which is why it converts so easily from hand to shoulder; the Kelly Pochette has no strap at all.
How Kelly size affects resale value
As with the Birkin, the smallest sizes command the strongest premiums. In our experience, leather Mini Kelly 20s often sell for $25,000 to $40,000 and exotic examples for $55,000 to $80,000, while leather Kelly 25s and 28s typically trade between $20,000 and $40,000. Vintage Kelly 32s and 35s often sell for $8,000 to $12,000. Past performance does not guarantee future value.
