Hermès Birkin 30 vs 35: which size carries your day
The Birkin 30 measures 30 x 22 x 16 cm and the Birkin 35 measures 35 x 25 x 18 cm. The 35 is 5 cm wider, 3 cm taller and 2 cm deeper: a box of 10,560 cm³ against 15,750 cm³, 49% more, which is the point where the bag is also a small travel bag.
Once buyers have settled on a Birkin at all, the 30-versus-35 question is the one that decides whether they buy a handbag or a carrying bag. The 30 closes over a normal daily load and keeps the shape it was made with; the 35 is the tier where the bag carries papers, a scarf and a bottle without any of them being squeezed into the corners.
The figures below are the published record for each tier, 30 x 22 x 16 cm and 35 x 25 x 18 cm, read as width x height x depth. Nothing here is measured from a sample: both sizes are quoted from the same record the model ladder uses.
Both sides of this comparison are published figures from the same records the model pages use, so the centimetres here and the centimetres there cannot disagree.
Hermès Birkin 30 vs Hermès Birkin 35: published sizes side by side
The two tiers in published centimetres, converted to inches and compared column by column.
| Measurement | Hermès Birkin 30 | Hermès Birkin 35 | Difference (A → B) |
|---|---|---|---|
| Width | 30 cm / 11.8 in | 35 cm / 13.8 in | +5 cm / +2.0 in wider |
| Height | 22 cm / 8.7 in | 25 cm / 9.8 in | +3 cm / +1.2 in taller |
| Depth | 16 cm / 6.3 in | 18 cm / 7.1 in | +2 cm / +0.8 in deeper |
| Box volume (derived) | 10,560 cm³ | 15,750 cm³ | +5,190 cm³ (+49%) |
| What the figure says fits | An everyday structured load: wallet, pouch, keys and a folded scarf. | A travel-friendly day bag: documents, a tablet and clothing for one night. | see the capacity section below |
Inches are the same centimetres divided by 2.54 and rounded to one decimal, exactly as on the model pages, so no page on this site carries a second set of inch values. Box volume is arithmetic on the three published figures (width × height × depth) — it is a scale comparison, not a published capacity rating, because a rounded or slouched body never fills its own box.
Capacity: what fits in each one
Five centimetres of width and three of height sound modest until you put the two bags next to each other, and the depth change decides how the bag sits when full.
The 30 is the tidier of the two. A long wallet, a phone, keys, a compact and a pouch fit without the body bulging, and the top closes flat so the silhouette stays upright in the hand. What it does not do well is take anything stiff and wide: a folder or an unopened magazine pushes the front and back panels apart and the bag immediately looks full.
The 35 is different in kind, not just in degree. The extra 5 cm of width takes a folded document or a slim portfolio, the extra height takes a taller bottle or a tablet in a sleeve, and the 2 cm of depth keeps a scarf beside a wallet instead of on top of it. It is still a handbag and still closes on the sangles, but it is the tier that people also use for a night away.
Hermès Birkin 30: what people carry
- A long wallet, a phone, keys and a compact arranged across the base rather than stacked
- A small pouch or a folded scarf in the space that is left at one end
- A tablet in a sleeve if the wallet is trimmed back to a card holder
- Everything closed flat, so the body keeps its shape in the hand
Published fit note: An everyday structured load: wallet, pouch, keys and a folded scarf.
Hermès Birkin 35: what people carry
- A folded A4 document or a slim portfolio lying across the base
- A taller water bottle or a tablet standing at one end
- A scarf, an umbrella and a pouch alongside the wallet rather than instead of it
- A change of clothes for one night if the bag is packed flat rather than rolled
Published fit note: A travel-friendly day bag: documents, a tablet and clothing for one night.
The two lists above describe how the sizes are carried in practice; the fit notes are the published descriptions that travel with the millimetres in the size records.
Which one suits which buyer
The choice usually comes down to two things: whether the bag has to close over paper, and whether the person carrying it prefers a compact or a substantial hand feel.
Buyers who settle on the 30 tend to have already tried something bigger and decided they do not want the weight. The 30 handles a normal wallet-and-phone day, keeps its structure, and looks the same at the end of the day as it did at the start. It is also the more formal-looking of the two when it is carried closed.
The 35 appeals to buyers who want one bag to cover working days and short trips: the load is heavier but the bag carries it without strain, and the extra height means the opening stays clear when it is full. Buyers who carry a laptop should still look at a dedicated work bag, because even at 35 cm the handles and the shaped base are not built for a flat computer.
Choose the Hermès Birkin 30 if…
- You want the closed-top handbag look and a load that never exceeds a wallet and a phone
- You carry the bag in the hand or on the forearm for most of the day
- You want the lighter of the two when both are empty
- Your daily essentials fit in something smaller than a folder
Choose the Hermès Birkin 35 if…
- You carry paper — a portfolio, a notebook or documents that must lie flat
- You want one bag for a working day plus an overnight
- You prefer the bag to balance on the forearm rather than hang from the hand
- You would trade some formality for the extra width and height
Questions buyers ask about the Hermès Birkin 30 and the Hermès Birkin 35
How much bigger is the Birkin 35 than the 30?
Five centimetres wider, three centimetres taller and two centimetres deeper: 30 x 22 x 16 cm against 35 x 25 x 18 cm. In box terms that is 15,750 cm³ against 10,560 cm³, a 49% increase, so the 35 is half again the volume of the 30 rather than a small step up.
Does the Birkin 35 look oversized on a smaller frame?
It reads as a substantial bag, because 35 cm across is close to a tote. If you are deciding by proportion, the 30 keeps a classic handbag line on most frames while the 35 sits wider along the body. Neither is wrong; the 35 simply announces itself more.
Can I use the Birkin 35 as a work bag?
For paper, yes — a slim portfolio or an A4 folder lies flat across the base. For a laptop, no: the shaped base and the two short handles are not designed around a flat computer, and carrying one in the bag pulls the body out of shape. A dedicated work tote is the better answer.
Which of the two holds its shape better when it is full?
The 30, because it is rarely pushed past its published depth of 16 cm. The 35 has 18 cm to give, so it also holds its line when loaded, but a wider body shows a heavy load sooner along the base. Both keep their shape best when the load lies flat rather than stacked.
How do I check which of the two sizes is in a listing?
Ask for a measurement photo with the bag flat, then compare it with 30 x 22 x 16 cm or 35 x 25 x 18 cm. The album reference printed on the photo identifies the individual piece, so the measurements and the listing can be matched to the same bag.

Inch values are converted from these centimetres; nothing on this page is a measured sample, an average of two records, or a rounded figure from a listing title. Where a family record carries two published values for the same tier, both are printed on the family ladder rather than one being averaged away.
