registers. Can you help

Sorry, you can't do that. For investment registers, the Account Bar, the Menu Bars, etc., the font type and size is taken from your Windows Display settings.

Font size problems? Display issues? (Windows)

If you are using a version of Quicken at the Quicken 2019 US R 19.44 patch level or newer and you have previously made the following Compatibility change, please undo the change.
Users of other Quicken versions please try the following:

• Close Quicken !!! (This process won't work while Quicken is running!)

• Check the Compatibility tab settings in your Quicken Desktop program icon:

• In the Windows Start Menu right-click the Quicken icon. Select "Open File Location". This brings up a Windows File Explorer window. Right-click the highlighted Quicken shortcut line item.
  or
• Go to the traditional Windows Desktop and right-click the Quicken program icon.
• Now click Properties.
• Select the Compatibility tab.
• Uncheck all settings.

• Windows 7, 8.1: Check "Disable display scaling on high DPI settings". 
  Windows 10:  Check "Override high DPI scaling behavior. Scaling performed by:" and select "Application"  (also try the other available options repeating the entire procedure!)

• Be sure to uncheck the "Run this program in compatibility mode for [older Windows version]" setting.

• Click the "Change settings for all users" button.
• Click Apply and exit.

• Now start Quicken and see if that makes a difference.

Some additional tuning suggestions:

• Try this workaround for 4k monitors

• Unless absolutely required, try not to use "View / Use large fonts"
• Try setting the bank account registers to use a different font style or size: go to Edit / Preferences / Register, click the Fonts button and try different fonts.
• Try adjusting the bank account registers' row height: go to Edit / Preferences / Register, choose among the available Row Height choices: Compact, Comfortable or Standard
• If all else fails, try changing Windows Control Panel / Display options for "Make text and other items … smaller or larger" to use a different scaling level.
