Thanks Chris,
We ended up "solving" this issue by changing the harcoded value, for now
it is working but it will be interesting to see how the system behaves
after more use.

Hi,
I am using koha to print labels with barcodes for books, however
am wondering if it is possible to increase the height of the
barcodes generated without increasing the width.
In the last version we were working with these barcodes had a
height of around 10mm for us, however this has now halved and
users are finding it difficult to get used to.
Unfortunately the current scaling code scales ultimately based on some
arbitrary hard coded value. Maintaining consistency across all barcode
widths with the current PDF::Reuse API is a bit challenging and would
become more so by allowing the user to choose. For example, if one
chose a particular size W x H, the bar width tends to become very
large as the number of chars in the actual alpha-numeric barcode
becomes smaller because PDF::Reuse attempts to maintain W x H. The
current Koha code attempts to maintain a reasonable W x H for all
possible barcodes. And it does not do even this extremely well. Try
generating barcodes for '1' versus '1234567890' to see the problem.
This is all from my memory as its been a while since I've had a look
over that code.
Kind Regards,
Chris
