Spacing between lines

I’ve created a font for Excel.
The row heights in Excel are automatically adjusted.
If I have a merged cell with 10 lines, I expect there to be a match with 10 individual lines as shown.
But there is no match.

What am I missing?

Excel is something special, it seems it has never been updated in the last two decades, so works in mysterious ways.

You could try to ask support at Microsoft.

Thanks for responding.
Can you please list all the user-inputs in FontCreator which may affect the vertical spacing.
I’ve spent hours trying to get to the bottom of it.

Please advise as best as you can, as this is important.

Yes I do agree that part of the issue is due to Excel, and also the printer driver … but please advise as best as you can.

We have explained it in this tutorial:

Font Metrics – Vertical Line Spacing

Yes I have seen that.
It hasn’t resolved the issue.
