Kern On

I'm working on a duplexed font and wanted to ask if there is a way to copy kerning so that there is no text reflow on changing styles.

If your metrics are shared between masters you could use the custom parameter “Link Metrics With Master”. Then Kern On will understand your intention and use identical kerning. See also this post.

Would that work in your case?

Tim, What do you think of the idea of just copying the metrics data from one master to the other? Would that provide an identical result? Would both result in the same data size in the saved font?

Thanks Tim, it is working like a charm! Earlier I was thinking of the same method shared by Eben but linking feels more efficient since I don't have to worry about any changes made to the main master.

PS. I really appreciate your work Kern-On. Thanks a ton :)

Hi Eben, what exactly do you have in mind? Do you mean copying the sidebearings from one master to the other? Would they have very similar shapes?

No, I meant going into the kerning window for one master and copying that data and pasting it into another master.

It's probably a dumb idea in practice but I was still curious about the data size question
