The quickest way to change font size in LMStudio

Open LMStudio and look at the bottom right corner of the window. You will see a small A with a plus sign and an A with a minus sign — these are your font size controls. Click the plus sign to make text larger, or the minus sign to make it smaller. Each click changes the size by one step.

If you prefer keyboard shortcuts, hold Ctrl (on Windows or Linux) or Command (on Mac) and press the plus key to enlarge text, or minus key to shrink it. You can also hold Ctrl or Command and scroll your mouse wheel up or down to adjust size continuously.

The change takes effect when ready in the chat window where you read responses from the language model. Your preference stays saved the next time you open LMStudio, so you only need to set it once.

Key Takeaways

  • The font size buttons are in the bottom right corner of the LMStudio window, marked with A symbols and plus or minus signs.
  • Keyboard shortcuts work faster: hold Ctrl (Windows/Linux) or Command (Mac) and press plus or minus to adjust size.
  • Your font size preference saves automatically, so the next time you open LMStudio it will be the same size you left it.
  • Font size changes only affect the text you read in responses — it does not change the size of buttons, menus, or the text you type into the chat box.

Where the font size controls are located

LMStudio puts the font size controls in the lower right area of the main window, next to the chat input box. Look for two small buttons: one shows a large A with a + symbol, and the other shows a small A with a − symbol. They sit close together, usually near the corner where the chat window ends.

If you are using LMStudio on a small screen or a narrow window, these buttons might be harder to spot. Try widening the window or scrolling down slightly in the chat area — the buttons should appear once there is enough space at the bottom right.

Using keyboard shortcuts instead of clicking buttons

Keyboard shortcuts are faster than clicking if you adjust font size often. On Windows or Linux, hold down Ctrl and press + (the plus key on your keyboard) to make text larger. Press Ctrl and − (minus) to make it smaller. On Mac, use Command instead of Ctrl.

You can also hold Ctrl (or Command on Mac) and roll your mouse wheel forward to enlarge text, or backward to shrink it. This method gives you finer control because you can adjust size in smaller steps without clicking multiple times.

What changes and what does not change

When you adjust font size in LMStudio, only the text in the response area gets larger or smaller — the text the language model writes back to you. The size of menu items, button labels, and the text input box where you type your questions stays the same.

This design means you can make responses easier to read without accidentally making buttons or controls too large or too small. If you need to change the size of the entire interface (menus, buttons, and all), that is a different setting in your operating system, not in LMStudio itself.

How LMStudio remembers your font size choice

LMStudio stores your font size preference in a settings file on your computer. Once you set the size to what you like, close the program, and open it again, the text will be the same size you left it. You do not need to adjust it every time.

If you use LMStudio on multiple computers, each one keeps its own font size setting. Changing the size on your laptop does not affect the size on your desktop — each device has its own saved preference.

Resetting font size to the default

If you want to go back to the original font size, you can click the minus button repeatedly until the text returns to normal, but that takes many clicks. A faster way is to look in the LMStudio menu for a View or Settings option that includes a Reset or Restore Defaults choice.

The exact menu location depends on which version of LMStudio you have, but it is usually under View at the top of the window. If you cannot find a reset option, you can also delete the LMStudio settings file from your computer, which will restore all defaults including font size — though this will also reset any other preferences you have changed.

Frequently Asked Questions

Does changing font size in LMStudio affect how the model responds?

No. Font size is only a display setting on your screen. It does not change what the language model writes, how long responses are, or how the program works. It is purely for your own reading comfort.

Can I set different font sizes for different chats?

No. LMStudio uses one font size setting for the entire program. Every chat window and every response uses the same size. If you want different sizes for different tasks, you would need to adjust the size each time you switch between them.

What if the font size buttons are not visible in my window?

Make sure the LMStudio window is large enough and not minimized. Try widening the window or scrolling down in the chat area. If buttons still do not appear, use the keyboard shortcut instead: hold Ctrl (or Command on Mac) and press plus or minus.

Will my font size setting stay if I update LMStudio?

Usually yes, but it depends on how the update is installed. Most updates preserve your settings. If you update and the font size resets, you can straightforward adjust it again and it will be saved for the next time.
