It is part of our comparisons hub and connects to our size and lifestyle guide.
Why dimensions matter
Dimensions matter because they determine a bag’s capacity, wearability and proportions on the body. Choosing a size that suits what you carry and your frame is essential to being happy with a bag, as a bag too small may be impractical while one too large may feel unwieldy. Understanding the dimensions of different models and sizes helps you make an informed choice that fits your needs and style.
A dimensions chart provides a quick, clear way to compare sizes across the range, helping you visualise how different bags relate to one another. This reference is invaluable when deciding between sizes or models, ensuring you choose proportions that work for your lifestyle and frame, as our bag scale guide explores.

Birkin sizes
The Birkin comes in several sizes, most commonly the 25, 30 and 35, with the numbers indicating the approximate width in centimetres. The 25 is the petite, collectible size suited to essentials; the 30 is the versatile everyday size balancing capacity and wearability; and the 35 is the large, roomy size for those who carry more. Each offers a different balance of capacity and proportion, so choosing depends on your needs.
Understanding the Birkin size range helps you select the proportion that suits you, from the adorable 25 to the practical 30 to the spacious 35, as our Birkin 25 guide and size comparison explore.
Kelly sizes
The Kelly also comes in several sizes, including the Mini Kelly (around 20cm), the 25, 28 and 32, with the numbers indicating approximate width. The Mini Kelly and 25 are petite, coveted crossbody sizes; the 28 is a beloved everyday size; and the 32 offers roomier everyday capacity. The Kelly’s structured silhouette and shoulder strap make each size versatile, with the choice depending on your capacity needs and preference for proportion.
From the intensely coveted Mini Kelly to the practical 28 and roomier 32, the Kelly size range offers options for every need, so understanding the dimensions helps you choose the ideal Kelly size for your life.

Small bags
Beyond the Birkin and Kelly, Hermes offers many small bags with their own dimensions, including the Constance 18, the Picotin in various sizes, the Evelyne range, and others. These smaller bags offer petite, wearable proportions suited to essentials and crossbody wear, and understanding their dimensions helps you compare them with the icons and with one another when choosing a small bag, as our crossbody guide explores.
How to use the chart
To use a dimensions chart effectively, start by assessing what you carry and your frame, then find sizes that suit both. Consider whether you want a petite essentials bag, a versatile everyday size, or a roomy tote, and use the dimensions to compare options. Remember that width is only one factor – depth, height and shape also affect capacity and proportion – so use the chart alongside consideration of how a bag will actually work for you, as our lifestyle guide details.
Depth and height matter too
While width is the headline dimension, depth and height significantly affect a bag’s real capacity and proportion. Two bags of the same width can hold quite different amounts depending on how deep and tall they are, so considering all three dimensions gives a truer picture of capacity. A structured bag and a soft bag of the same width may also carry differently. When choosing, look beyond width alone to understand how much a bag will actually hold and how it will proportion on your frame, as our bag scale guide explores.
Factoring in depth and height alongside width ensures you choose a bag whose true capacity and proportions suit your needs, avoiding surprises about how much fits.
Dimensions and body proportion
Dimensions also relate to how a bag looks on your body. A size that flatters one frame may overwhelm or underwhelm another, so considering your height and build alongside the bag’s dimensions helps you choose flattering proportions. Petite individuals may prefer smaller sizes that do not overwhelm, while taller individuals may carry larger sizes beautifully. Matching bag scale to your frame is key to a harmonious look, as our dedicated bag scale guidance details.
Comparing across models
A dimensions chart is especially useful for comparing across different models, helping you see how, say, a Kelly 28 relates to a Birkin 30 or a Constance 18. Because models have different shapes, comparing dimensions alongside their designs helps you understand the practical and aesthetic differences. This cross-model comparison is invaluable when choosing between different bags, allowing you to weigh size against style, as our comparisons hub supports.
Dimensions and travel
For travel, dimensions take on added importance, as you may want a roomier bag for carrying more or a secure crossbody for convenience. Understanding the capacity of different sizes helps you choose a travel-appropriate bag, whether a spacious tote for essentials on the go or a compact crossbody for hands-free security. Considering dimensions in the context of travel needs ensures a practical choice, as our lifestyle guide explores.
Using dimensions wisely
The wisest approach to dimensions combines the chart with real consideration of your needs, frame and style. Use the numbers to compare and shortlist, but also picture how a bag will work for what you carry and how it will look on you. Where possible, seeing or trying a bag in person confirms the dimensions in reality. Used thoughtfully, dimensions guide you to a bag whose size truly suits your life.
The value of a size chart
A good size chart is one of the most practical tools a Hermes buyer can consult, distilling the sometimes confusing array of models and sizes into a clear, comparable overview. It removes guesswork, letting you see at a glance how sizes relate and which might suit your needs, and it is especially valuable when buying remotely or deciding between options. Kept handy as a reference, a dimensions chart empowers you to make informed size decisions with confidence, ensuring you choose proportions that truly work for your life and complementing the deeper guidance in our size and lifestyle guide.
