The fastest way to judge a replica Hermes bag is a tape measure, not a photo. Measure four points (body width, body height, base depth, handle drop) and compare them to the published numbers for that model. A replica Birkin 30 that measures 32 cm across is not a size 30 with a tolerance issue. It is a different pattern, and it will sit wrong on the arm and in a dust bag.

What You Are Comparing
Hermes lists a bag by its width in centimeters. Birkin 25, Kelly 28, and Constance 18 all refer to the body width in a closed position, gussets included. Height runs from the base to the top edge of the back panel, without the handle. Depth is the base gusset. Handle drop is the clear space between the top of the handle and the top edge of the bag.
Those four numbers move together. When one is off, the others are off too, because the pattern was scaled from a photo instead of drafted from a spec sheet.
Tools You Need
- Soft fabric tape measure, the sewing kind
- Ruler or calipers for the handle drop
- A flat table and a rolled towel to hold the bag upright
- The model name and size you are comparing against
How to Measure a Fake Hermes Bag
- Empty the bag and close the flap or the turn lock.
- Set it on a flat table and support the sides so the body keeps its shape.
- Measure body width across the widest point, from the left edge of the gusset to the right edge.
- Measure body height from the base seam to the top edge of the back panel, skipping the handle.
- Measure base depth at the bottom gusset, front to back, with the bag unstuffed.
- Measure handle drop from the top of the handle arc down to the top edge of the bag.
- Measure the front flap width and the spacing of the base feet.
- Write all six numbers down before you compare them to the size chart.
Reference Numbers for Common Sizes
Birkin
- 25: about 25 cm wide, 20 cm high, 13 cm deep
- 30: about 30 cm wide, 22 cm high, 16 cm deep
- 35: about 35 cm wide, 25 cm high, 18 cm deep
- 40: about 40 cm wide, 30 cm high, 21 cm deep
- Handle drop: about 9 to 10 cm on the 25 and 30, about 10 to 11 cm on the 35 and 40
Kelly
- 25: about 25 cm wide, 19 cm high, 9 cm deep
- 28: about 28 cm wide, 22 cm high, 11 cm deep
- 32: about 32 cm wide, 23 cm high, 12 cm deep
- 35: about 35 cm wide, 24 cm high, 12 cm deep
Kelly numbers split by construction. Sellier has a rigid, squared shape and reads close to the listed width. Retourne is softer and can measure half a centimeter wider across the body because the leather relaxes.

Constance
- 18: about 18 cm wide, 15 cm high, 5 cm deep
- 24: about 24 cm wide, 18 cm high, 6 cm deep
Normal Variance vs a Wrong Size
Handmade bags are cut and sewn by hand, so 0.3 to 0.5 cm of drift is normal, and leather choice changes it. Togo and Clemence relax with use. Epsom and Box hold their shape. A bag that lands inside 0.5 cm on all four numbers matches the size. A bag that is 1.5 cm or more off on width is either a different size or a scaled pattern, and no amount of stitching quality fixes that.
Dimension Red Flags
- Width matches but depth is short by 2 cm, so the bag looks flat from the side
- Handle drop under 8 cm, so the bag will not clear a wrist
- Kelly 28 body measuring 30 cm, a common result of stretching a 25 pattern
- Feet spaced wider than the base plate, leaving the bag rocking on a table
- Flap wider than the body, which shows as a lip over the gusset
- Strap length that does not match the size, since Kelly straps scale with the body
Questions for a Supplier
- Ask for the measured width, height, depth, and handle drop in centimeters, not the model name alone.
- Ask which leather the sample was cut from, because Togo and Epsom finish at different widths.
- Ask for a photo of the bag beside a ruler at the base.
- Ask whether the size is a true pattern or a scaled version of a larger bag.
Numbers do more work than photos here. A supplier who can quote four measurements to the half centimeter is working from a real pattern.
