Hermès Kelly Sizes Explained: 25 vs 28 vs 32 — Which To Buy in 2026
You've done the work. You've built the relationship, you've bought the scarves and the boots and the tableware, and your sales associate finally says the words: "I have a Kelly for you." Then comes the question that determines whether you carry this bag for thirty years or quietly resell it in eighteen months.
Which size?
Most buyers say 25 without thinking, because that's what the resale market screams and what fills every Instagram feed. Sometimes that's right. Often it isn't. The Kelly 25 is genuinely small, the 28 is the size Grace Kelly actually carried, and the 32 is the one people rediscover in their forties and never put down.
This guide breaks down all three by real capacity, proportion on different frames, price, resale behavior, and the honest tradeoffs nobody mentions in the boutique.
Quick Reference: Kelly Sizes and 2026 Prices
Sizes are measured across the base in centimeters. Prices are US retail for Kelly Sellier and Retourne in standard calfskin (Epsom, Togo, Clemence) with palladium or gold hardware, reflecting 2026 pricing after the January adjustment.
| Size | Base Width | Height | Depth | 2026 US Retail (approx.) | Weight Feel | |---|---|---|---|---|---| | Kelly 25 | 25 cm | 19 cm | 9 cm | $12,500 – $14,000 | Light, ~2 lb | | Kelly 28 | 28 cm | 22 cm | 10 cm | $13,500 – $15,200 | Moderate, ~2.4 lb | | Kelly 32 | 32 cm | 23 cm | 10.5 cm | $14,500 – $16,500 | Noticeable, ~2.9 lb |
Context on the rest of the family: the Mini Kelly II (20cm) runs roughly $11,500 – $13,000 at retail but trades far above that on the secondary market. The Kelly 35 ($15,500 – $17,500) has largely fallen out of favor. Kelly Pochette sits around $10,000 – $11,500. Exotic skins start near $40,000 and climb steeply.
Add roughly 8–15% for Swift or Barenia Faubourg, and expect meaningful premiums on limited seasonal colors, Sellier construction in certain leathers, and any bag with contrast stitching or special-order specs.
Kelly 25: The One Everyone Wants
Real capacity: Long wallet or compact wallet, phone, key pouch, lipstick, sunglasses in a soft sleeve. Add a compact and you're at the limit. A hardshell glasses case and a full-size water bottle will not both fit.
The 25 is the most in-demand Kelly on earth right now, and demand is doing something strange to it: retail is roughly $13,000, but a well-specced Kelly 25 in Epsom with gold hardware routinely resells above retail on the secondary market. That's rare even within Hermès.
Who it suits. Petite frames, minimalists, anyone under about 5'5" who doesn't want a bag dominating their silhouette, and anyone treating the purchase partly as an asset. It photographs perfectly, it works from lunch to dinner, and it never looks like luggage.
The honest downside. It's small. Many owners buy the 25 for its resale strength, then find themselves carrying a tote for actual belongings and the Kelly for show. If you currently carry a bag with a notebook, an iPad, or a lunch in it, the 25 will frustrate you. Sellier construction makes it feel even smaller because the rigid sides don't give.
Kelly 28: The Original Proportion
Real capacity: Everything from the 25, plus a small notebook, a proper glasses case, a larger cosmetics pouch, and a slim folder if you angle it. This is where the bag becomes genuinely functional without becoming a workbag.
The 28 is what Grace Kelly carried and what the bag was proportioned around. It's the size that looks most "correct" in the hand and on the arm for average heights. Hermès insiders often quietly consider it the best-balanced Kelly.
Who it suits. Anyone 5'4" to 5'9", anyone who wants one Kelly to cover work and evening, and anyone who values daily usability over maximum resale multiple. Retourne 28 in Togo is one of the most livable configurations Hermès makes — soft, forgiving, roomy enough.
The honest downside. Resale is strong but not the frenzy you see at 25. You'll typically recover a healthy percentage of retail rather than a premium. And in Sellier with rigid Epsom, the 28 can read slightly formal for casual weekends.
Kelly 32: The Quiet Favorite
Real capacity: A 13-inch laptop sleeve in some configurations, a folder, a water bottle, a full cosmetics bag, and everyday essentials. This is a working bag.
The 32 fell out of fashion during the mini-bag decade and is now the best value in the Kelly lineup at retail. Boutiques are more willing to offer it, the price gap over the 25 is modest relative to the capacity gain, and it's the size that professionals with actual things to carry end up loving.
Who it suits. Taller frames (5'8" and up), professionals, mothers, anyone who resents carrying two bags. On a tall person a Kelly 32 looks proportional in a way the 25 simply cannot.
The honest downside. Weight. A loaded Kelly 32 in Togo carried by the top handle gets tiring, and the shoulder strap on a Kelly is a single thin strap with no padding. It also reads dated to some buyers, and resale percentages trail the smaller sizes.
Sellier vs Retourne: The Choice Behind the Choice
Size isn't the only decision. Every Kelly comes in one of two constructions, and it changes the bag more than 3cm of width does.
Sellier stitches the leather with seams on the outside, producing crisp edges and a rigid, architectural bag. It stands up on its own, holds shape indefinitely, and looks formal. It's typically done in Epsom or Box calf. It shows corner wear more visibly and offers zero flex on capacity.
Retourne is stitched inside out then turned, giving soft rounded edges and a slouchier, friendlier bag. Usually Togo, Clemence, or Swift. It's more forgiving, more casual, and lets you overfill slightly.
A rough rule: Sellier for formality and longevity, Retourne for daily comfort. In the smaller sizes Sellier is generally more coveted on resale; in the 32, Retourne is the more sensible choice.
Which Size Should You Buy?
Choose the Kelly 25 if you're petite, you carry little, resale value matters to you, or this is a special-occasion and dinner bag. Accept that it will not be your only bag.
Choose the Kelly 28 if you want one Kelly for the rest of your life and you want to actually use it. This is the default recommendation for most buyers. It balances proportion, capacity, and value better than either alternative.
Choose the Kelly 32 if you're tall, you work, or you refuse to carry a second bag. You'll pay a modest premium over the 25 and get dramatically more bag. Just be honest about the weight.
Skip all three and consider alternatives if none of this fits your life. A Bolide gives you a zipper and an included strap for less money and far less waiting. A Picotin Lock gets you into leather Hermès under $5,000. And if you haven't fully settled the flagship question, our Birkin vs Kelly guide is the place to start.
Hardware and Color: Small Decisions, Real Money
Hardware finish affects both look and resale. Gold hardware is the most requested and holds value best on neutral leathers. Palladium reads cooler and more modern, and pairs well with grays, blues, and blacks. Rose gold and brushed finishes appear on limited runs and can command premiums or discounts depending on the year.
On color: black, Étoupe, Gold (the tan), and Craie are the reliable value holders. Bright seasonal colors are more fun and less liquid — a Rouge Casaque Kelly is thrilling and harder to resell at a premium than a black one. Our resale value guide covers which combinations actually perform.
Kelly Sizes FAQ
Can you wear a Kelly crossbody? The included strap allows shoulder or crossbody wear depending on strap length and your height. The 25 and 28 crossbody comfortably on most frames; the 32 can look bulky crossbody. Strap lengths vary by production year.
Which Kelly size is hardest to get? The Mini Kelly 20, then the Kelly 25. The 28 is moderately difficult and the 32 is the most attainable of the three.
Is the Kelly 32 too big for 2026? No. Larger bags have been returning across the luxury market, and the 32 was never actually oversized — it just looked that way next to micro bags. On a tall frame it's the most flattering Kelly.
Does the shoulder strap come with every Kelly? Yes, standard Kellys ship with a detachable shoulder strap. Kelly Pochette does not include one.
How much do Kelly prices increase each year? Hermès has raised prices annually, generally 5–10%, with occasional regional adjustments mid-year. Waiting for a better price is not a strategy that works here — see our 2026 price increase breakdown.
Should I buy at retail or resale? Retail is cheaper for the 28 and 32 if you can get the offer. For the Kelly 25 and Mini, resale is often the only realistic path and you'll pay above retail for it.
What size did Grace Kelly carry? Predominantly the 28, in the Sellier construction that defined the bag's formal reputation.
