Fake Louis Vuitton bags usually miss the official dimensions by 0.5 to 2 cm (roughly 0.2 to 0.8 in), because most counterfeit workshops copy a photo instead of the real pattern. A tape measure is one of the fastest authenticity checks you can run at home. Measure the base, the height and the depth, then compare each number to the spec Louis Vuitton publishes for that model.
What are the official dimensions of the most faked Louis Vuitton bags?
These are the manufacturer-listed sizes for the models counterfeits copy most. Each figure is width by height by depth, taken at the widest point.
- Neverfull PM: 11.4 x 8.7 x 5.1 in (29 x 22 x 13 cm)
- Neverfull MM: 12.6 x 11.4 x 6.7 in (32 x 29 x 17 cm)
- Neverfull GM: 15.7 x 13 x 7.9 in (40 x 33 x 20 cm)
- Speedy 25: 9.8 x 7.5 x 5.9 in (25 x 19 x 15 cm)
- Speedy 30: 11.8 x 8.3 x 6.7 in (30 x 21 x 17 cm)
- Alma BB: 9.3 x 6.9 x 4.5 in (23.5 x 17.5 x 11.5 cm)
- Pochette Metis: 9.8 x 7.5 x 2.8 in (25 x 19 x 7 cm)
- Keepall Bandouliere 55: 21.7 x 12.2 x 9.8 in (55 x 31 x 25 cm)
How do you measure a Louis Vuitton bag correctly?
- Lay the bag flat on a table and let the canvas settle into its natural shape.
- Measure the widest point of the base for width, not the top opening.
- Measure from the base seam to the top edge for height, excluding handles.
- Measure the side panel at its deepest point for depth.
- Record the numbers in both inches and centimeters to catch unit swaps.
Which dimension errors show up most on fakes?
The clearest tell is a bag sold as one size that measures like another. A Speedy 30 that comes in at 28 cm across is closer to a Speedy 25 body fitted with 30 hardware. Depth is the second tell, since counterfeit patterns often flatten the side panel by a centimeter or more.
Handle drop and strap length drift too. Measure them end to end and compare against the spec rather than trusting a seller description.
Do dimensions alone prove a bag is fake?
No. Measurements are one data point. Canvas can relax by a few millimeters with use, and older pieces were assembled by hand with small tolerances. Pair the tape measure with date code placement, hardware weight, stitching density and a paid authentication service.
What should you do if the measurements are wrong?
Photograph the tape measure resting against the bag next to the published spec. Send both images to the seller or platform inside the return window. For higher-value bags, order a written authentication opinion before the window closes.
