Can’t scale FBA labels to fit the paper

Hi Reddit!

I am trying to print some barcode labels for my inventory; I am trying to print the 27–up labels onto A4 sheets with 63.5mm x 29.6mm label sizes.

However, no matter how I scale the labels, they never manage to fit the into the label sizes at all, which is costing me money in paper and ink trying to work out how to get them in the boxes.

Any advice?

Thanks
