Thanks for joining this conversation, @Krista-WR. Let's get your QuickBooks Online fonts changed.
To do this, you can hold the "Ctrl" key and press the "+" sign altogether on your keyboard. Or, hold the "Ctrl" key and then scroll up to change the font size.
For future reference, you also want to adjust the font size of your printed sales forms. See the attached link to guide you in modifying the Customs Form Styles window: Customise invoices, estimates, and sales receipts in QuickBooks Online,
Get back to me if you have additional concerns. I'll be there to help you again.
