Hi, The script of my invoices and bill have changed to a very small size, how can I make it bigger again?

Hello, esme. Allow me help you with this.

If the small size occurred in your sales form, you want to follow the steps below to adjust the script/text size to a bigger one for your invoices. 
 

1. Go to the Gear icon.
2. Select Custom form styles and select a template you want to apply to your invoice.
3. Click the Select a different font option.
   
4. Click the size drop-down arrow.
   
5. Hit Done to reflect the changes.

However, since you've included bills and the size changed suddenly, we can perform the steps below to fix it. 

1. Log in to your QBO in an incognito window.
   For Google Chrome browser: Ctrl + Shift + N
   For Mozilla Firefox browser: Ctrl + Shift + P
   For Safari browser: Command + Shift + N
2. Clear the cache.
3. Use other support browsers.

On the other hand, if it occurs in all areas, you can check your settings and change the size. The steps below work depending on the device and browser.

1. On your browser, click three dots icons (vertical icons).
2. Select the Settings option.
3. Go to the Appearance section.
4. Tick the Font size drop-down arrow. Then, choose your desired size.  
   
    

If you see different options, I'd recommend consulting someone or an IT expert who can guide you through adjusting the size of your device.
