Short answer
A Birkin 40 is the largest standard Birkin. Spec sheets list the base at 40 cm wide, 30 cm tall, and 21 cm deep, or 15.7 x 11.8 x 8.3 in. Replica Birkin 40 bags sell for about $80 to $1,500. Hermès does not publish Birkin prices and does not sell handbags online. A replica is a copy of a trademarked design, and US customs can seize imported copies.
What the number 40 means
Hermès sizes the Birkin by base width in centimeters: 20, 25, 30, 35, and 40. The number is not leather, hardware, or price tier. A Birkin 40 carries a 40 cm base. A Birkin 35 carries a 35 cm base. The 40 is 5 cm wider and 4 cm taller than the 35.
Measurements and weight
- Birkin 35: listed at 35 x 25 x 18 cm
- Birkin 40: listed at 40 x 30 x 21 cm
- Empty weight: listing figures place a Birkin 40 in Togo leather near 1.4 kg
- Loaded weight: 2.5 kg or more with a laptop and a folder
A 40 holds a 15-inch laptop, a document folder, a water bottle, and a small pouch. A 35 holds the folder and the pouch, and a 15-inch laptop is a tight fit. Height and depth change the feel more than the 5 cm width gap.
Build facts on the original

What replica sellers mean by mirror or 1:1
These are marketing terms, not a standard. No governing body certifies a replica tier. The words describe a claim from the seller. Ask four questions in writing: leather type, stitch method, hardware alloy, and stamp method. A seller who answers all four is telling you more than a photo set can.
Price bands
- $80 to $200: PU or bonded leather, machine stitching, painted edges, steel hardware
- $200 to $500: split-grain or embossed leather, machine stitching, some hand finishing
- $500 to $1,500: full-grain leather, hand saddle stitch, plated hardware, edge paint
Above $1,500 the price has no link to materials. Hermès does not license its name to any factory. No replica carries authorization.
Checkpoints before you buy
- Ask for the exact leather name, not the phrase genuine leather
- Ask for the stitch count per inch
- Ask for the hardware alloy and plating thickness
- Ask for a photo of the blind stamp and the date code
- Confirm the return window in days
- Check the hardware tone against photos; plated brass and palladium differ in color
Legal facts
Hermès holds registered trademarks on its name and on the Birkin trade dress. Under 19 U.S.C. 1526, US Customs and Border Protection can seize and destroy imported goods that carry a counterfeit mark. Selling counterfeit goods is a federal crime under 18 U.S.C. 2320. Buying one bag for personal use is not a federal crime, but the shipment can be seized and lost. France and Italy treat counterfeiting as a purchase offense as well. Rules differ by country, so check your own.
Recap
- Birkin 40: 40 x 30 x 21 cm, near 1.4 kg empty
- Replica prices: $80 to $1,500 across three build tiers
- Tiers track leather, stitching, and hardware, not the label
- Trademark law applies to the design and the name
- Import risk is real and the loss is the full price paid
