Is the default theme in Access the same on both PCs?

I can try this, but per Copilot, below.  I always use Arial font and when I copied the database to the client, it changed to a different font, which is weird as Arial seems to be on every pc.  

If your fonts are changing between PCs…
Changing the theme won’t fix that.
Your earlier issue (fonts shifting/cutting off text) is caused by:

Different DPI scaling

Different font versions

Different default printer drivers

Different Office UI themes

Changing the Access form theme only affects colors/fonts within the theme, not spacing or DPI behavior.

Kevin's on the right track. Access form themes can specify fonts, and if the two PCs are using different themes, the font can change even if you designed the form with Arial. Microsoft has also started using Aptos as the default Office font instead of Calibri, and Aptos is a little wider, so labels that were sized tightly can suddenly get clipped. I personally prefer Tahoma.

Personally, I stopped trusting themes years ago. It's one of the reasons I don't use them much in my classes. I explicitly set my fonts, colors, and other formatting instead of relying on theme settings. It might take a little more work up front, but it eliminates one more variable that can unexpectedly change the look of your application.

I'd compare the form theme on both machines first, then verify the actual font assigned to the label controls. If those match, I'd check Windows display scaling and make sure both PCs are running similar Office versions. I've also seen subtle differences in font metrics between Office updates that were enough to make labels that just barely fit start truncating.

Moral of the story: avoid themes. Leave a little extra space on the right side of your labels... just in case. :)

Thanks.  In 35 years of using and developing in Access, in all honesty, I have never dealt with themes.  I see that you can turn them off globally and on a form, so I will test that the next time I load the database...

That's the funny part - you may not have deliberately used themes, but newer versions of Access can still apply the current database or Office theme behind the scenes. If the label is explicitly set to Arial in the form's properties, though, it should normally stay Arial.

The next time it happens, open the form in Design View on both machines and compare one affected label's Font Name, Font Size, Font Weight, Width, and the form's Theme property. That should tell you quickly whether it is really a font/theme change or just a display/scaling issue.

And yes, if you are copying a front end to client machines, I would absolutely give every label a little breathing room. Labels sized to fit exactly are like a transporter with no safety margin - eventually something gets lost in transit.
