Privé Porter’s Guide To: The Ultimate Hermès Birkin & Kelly Size Guide
Choosing your first Hermès bag—or your next one—is about much more than color and leather. One of the most important decisions you'll make is size.
A Birkin 25 and a Birkin 40 may share the same iconic DNA, but they serve completely different lifestyles. The same goes for the Kelly family, where a Kelly 25 offers a polished evening silhouette while a Kelly 35 is built for everyday practicality.
To make shopping easier, we've created our Privé Porter Birkin and Kelly Size Charts, giving collectors a visual reference for how each size looks when carried.
Here's everything you need to know before choosing your perfect Hermès.
Understanding Hermès Sizes
Unlike many handbag brands, Hermès sizes refer to the approximate width of the bag in centimeters.
For example:
- Birkin 25 = approximately 25 cm wide
- Kelly 28 = approximately 28 cm wide
While a few centimeters may not sound like much, they dramatically change how the bag looks, feels, and functions.
Birkin Sizes Explained
Birkin 25
The Birkin 25 has become one of the most sought-after handbags in the world.
Compact yet surprisingly functional, it comfortably holds daily essentials while maintaining an elegant, structured silhouette. It's perfect for collectors who prefer lighter bags or want a sophisticated day-to-evening option.
Best for:
- Everyday luxury
- Lunches and dinners
- Petite frames
- Minimalists
Birkin 30
Many collectors consider the Birkin 30 the "Goldilocks" size.
Not too small. Not too large.
It offers noticeably more interior space than the 25 while remaining elegant enough for almost any occasion. If you're buying your first Birkin and want maximum versatility, the 30 is often the safest choice.
Best for:
- Everyday use
- Work
- Travel
- First-time collectors
Birkin 35
Before the Birkin 25 became today's collector favorite, the Birkin 35 dominated the fashion world.
Its generous proportions make it ideal for carrying a laptop, documents, or everything you need throughout a busy day. Recently, larger handbags have made a significant comeback, bringing renewed attention to this classic size.
Best for:
- Work
- Frequent travelers
- Parents
- Collectors who love oversized bags
Birkin 40
The largest standard Birkin is bold, practical, and undeniably iconic.
Originally designed with travel in mind, the Birkin 40 has become increasingly popular among both men and women looking for an elevated travel companion or oversized statement bag.
Best for:
- Weekend travel
- Business trips
- Men
- Fashion collectors embracing oversized silhouettes
Kelly Sizes Explained
Kelly 25
Elegant, refined, and endlessly versatile, the Kelly 25 has become one of Hermès' most desirable handbags.
Whether worn by the top handle or crossbody with the shoulder strap, it transitions effortlessly from daytime errands to evening events.
Best for:
- Everyday wear
- Evening occasions
- Crossbody styling
- Smaller frames
Kelly 28
For many collectors, the Kelly 28 offers the perfect balance between sophistication and practicality.
It provides additional interior space while maintaining the graceful proportions that have made the Kelly one of the world's most recognizable handbags.
Best for:
- Daily use
- Professionals
- Travelers
- First Kelly purchase
Kelly 32
The Kelly 32 has quietly become one of Hermès' most underrated sizes.
Relaxed enough for everyday use yet polished enough for business meetings, it's ideal for collectors who appreciate timeless elegance over fleeting trends.
Best for:
- Work
- Everyday carry
- Larger essentials
- Timeless style
Kelly 35
The Kelly 35 is built for collectors who refuse to compromise on space.
Its roomy interior makes it a favorite for work, travel, and anyone who carries more than just the basics. While smaller Kelly sizes often steal the spotlight today, the Kelly 35 remains one of Hermès' original classics.
Best for:
- Travel
- Work
- Parents
- Daily carry with extra space
Which Size Is Right for You?
There isn't a universally perfect Hermès size.
Instead, the best choice depends entirely on your lifestyle.
If you're looking for a compact everyday companion, a Birkin 25 or Kelly 25 may be perfect. If versatility is your priority, the Birkin 30 and Kelly 28 continue to be two of the most balanced options in the collection. And if you travel frequently or carry your entire day with you, the Birkin 35, Birkin 40, Kelly 32, or Kelly 35 may be exactly what you're looking for.
The beauty of Hermès is that every collector eventually discovers their own favorite.
Sometimes, it's not the smallest bag or the rarest bag that becomes your most loved.
It's simply the one you reach for every day.
