Preview being cropped

Hi all,
I’m new to Glyphs and can’t seem to find a way to preview my font fully in the Font Window. I imagine that’s an easy fix (regarding the height of my font…?) but haven’t found a solution yet… I’ve attached screenshots.

Thank you for the help!

This is probably because your Master metrics are not correctly set.
Be sure they are set according to the height of your letters.

Thank you @HugoJ ! Indeed they were not set correctly. May I ask what the numbers 16 or -16 are for?

Thank you!

Those are overshoots, important for hinting.

These are the sizes of the alignment zones (above baseline: +#, below baseline: -#, no zone: 0). Lean more in the Handbook:

Amazing! Thank you all for the quick answers!
