I have photographic prints for sale - linked to a drop shipping printer.

At the moment the size descriptions read something like - 21cm x 30cm, 8.3inches x 11.7inches.

I’d like to put “A4” before the measurements as that makes more sense.

I tried editing the Variants field on the product page and added A4 before one of the sizes.

However, this produced, multiple new size versions.

I’m obviously confusing the system doing it this way and I’m not sure my drop-shipping printer would connect to these new versions.

Does anyone know if there’s a way to simply change the size description so it appears on the customer’s page without messing with all the variants?

Many thanks
