Because when it comes to Kelly, size does matter.

Discover the ultimate Hermès Kelly bag sizing guide — from Mini Kelly to Kelly 35, learn the differences between Sellier and Retourne, strap options, and how to choose the perfect size for your lifestyle.

 

Introduction: The Bag That Defined Quiet Luxury

 

There are handbags, and then there is the Hermès Kelly — a piece of living fashion history. Structured, elegant, and impossibly timeless, the Kelly isn’t just a bag; it’s an heirloom, an obsession, and in many cases, a milestone.

Named after Princess Grace Kelly of Monaco, who famously used it to shield her baby bump from the paparazzi in the 1950s, the bag has since become a symbol of understated luxury. But before you fall head over heels for its silhouette, there’s one essential detail to consider: size.

Hermès Kelly bags come in a range of dimensions — from petite treasures to bold, statement-making staples. Each size tells a different story, suits a different lifestyle, and deserves its own moment in the spotlight.

So, let’s dive into the details and decode the differences. Whether you’re shopping for your first Kelly or adding to a well-curated collection, this guide will help you find the one.

 

The Kelly Sizes at a Glance

Hermès Kelly bags are named by their length in centimeters. Here’s a breakdown of the most common sizes:

Note: The Kelly 15 and 20 are often called “Mini Kelly” sizes — highly coveted, very limited, and almost impossible to score without a waitlist and a wink.

 

Sellier vs. Retourne: It’s Not Just About Size

 

Before you even choose your Kelly size, you need to know your style:

• Sellier: Sharp, structured edges. A bit more formal and architectural. Think power lunch in Paris.
• Retourne: Softer, more relaxed construction with turned-in seams. Easier for everyday wear with a touch of nonchalance.

Both styles come in various sizes, and the shape can affect how the bag wears and even how big it feels.

 

 

Which Kelly Size Is Right for You?

Let’s break it down by lifestyle and intention:

The Collector’s Darling: Kelly 20 or Kelly 25

These sizes are the darlings of the fashion elite. Small enough to be precious, big enough to hold essentials (especially the 25), and timelessly elegant. Perfect for those who love a bag that can go from gallery opening to dinner party without missing a beat.

 

The Everyday Icon: Kelly 28 or Kelly 32

Functional and chic. These sizes offer the perfect balance of structure and space. They fit phones, wallets, glasses, and even a mini agenda — ideal for women who live full lives but never compromise on style.

 

The Understated Power Move: Kelly 35+

A larger Kelly speaks softly but carries everything. Whether you’re traveling or need a more substantial look, the 35 and up are less common today, but oh-so-stylish in the right hands. Think minimal outfit, major bag.

 

 

Strap Talk: Shoulder-Friendly or Strictly Top Handle?

 

All modern Kelly bags come with a detachable shoulder strap (except some vintage minis), which makes even the more structured Sellier styles easy to carry. The length of the strap depends on the size — larger bags tend to come with longer straps, but many opt to swap them for crossbody chains or custom straps for added flair.

 

Final Word: The Kelly Is Personal

The beauty of the Kelly is that it’s not just a fashion statement — it’s an extension of your style, your story, and your pace of life. Whether you’re tucking a Kelly 20 under your arm or swinging a Kelly 32 from your wrist, you’re carrying a piece of elegance that transcends seasons and trends.

So take your time, do your research, and when you find your Kelly — trust us, you’ll know.
