Clarify the size of new Wallet on strap

[apple182]

Hi everyone
I bought a new wallet on strap from a reseller and I just find out that the size of my bag is 20cm when on Celine website is 22cm
Is it normal
If you have same bag pls can you clarify the true size

I have the canvas and leather trim one and it's 19.5 cm wide. I got it directly from the boutique.

Celine's measurements on the site are not accurate - it lists both the triomphe shoulder bag and triomphe WOC as 8 inches (20cm vs 19.5 cm) but when I compared both at the boutique, the shoulder bag definitely seemed more than .5cm longer. It 100% fits more than the WOC too. I went in thinking I would get the WOC since on the site it's "the same size" if not slightly taller, but ended up with the shoulder bag for this reason.
