I have a workbook with two different worksheets. In order to get the column widths to look physically alike I have to set them 8.75 (75 pixels) on one and 10 (75 pixels) on the other. I assume this is something to do with the overall font for each individual worksheet because the column header bar has a different appearance.

However, I don't know how to change this font (if indeed that is the problem). The fonts from the Themes menu for both worksheets show Heading: Calibri Light and Body:Calibri. The only other settings that I can think of (in options) would appear to apply to all woksheets, which won't help. Has anyone a suggestion?

I have Professional Plus 2019.

The fonts listed on the Themes Menu may not show the whole formatting.
If you wish to have the same column widths and/or formatting, you can use the many Paste Special options.
Instead of CTRL+V to paste, use ALT, E, S, V and choose the options desired.

Each worksheet can be zoomed to different percentages. Check the settings under View > Zoom for both sheets - are they the same percentage?
