If you’ve ever opened Google Slides and found the interface, spell checker, or text input in the wrong language, you’re not alone. Whether you’re collaborating with an international team, preparing a multilingual presentation, or simply working in your native language, getting the language settings right saves time and prevents frustrating errors.
This guide covers 3 clear methods to change language settings in Google Slides — from switching the full interface language to adjusting spell check for individual text blocks — so your presentations always work exactly the way you need them to.
Why Language Settings Matter in Google Slides
Google Slides is part of Google Workspace, and its default language follows your Google Account settings. But that one-size-fits-all default can cause real problems:
- Spell check flags words incorrectly when your content language doesn’t match the interface language.
- International collaborators may struggle if the interface is locked to a language they don’t read fluently.
- Multilingual presentations require fine-grained control — paragraph by paragraph — to keep spell check accurate.
Understanding which setting controls which layer of language behaviour is the key to fixing all of these issues cleanly.
Method 1: Change the Google Slides Interface Language (Via Google Account)
The interface language — menus, buttons, dialogs — is controlled at the Google Account level, not inside Google Slides itself. Here’s how to change it:
Step 1: Open Your Google Account Settings
- Go to myaccount.google.com or click your profile picture on any Google page.
- Select “Manage your Google Account.”
Step 2: Navigate to Language Preferences
- Click on the “Data & Privacy” tab (previously called “Data & Personalization”).
- Scroll down to “General preferences for the web.”
- Click “Language” → then “Edit.”
Step 3: Select Your Preferred Language
- Use the search box or scroll to find your language.
- Click it, then hit “Select.”
- Confirm the change — Google may ask you to verify.
Step 4: Verify in Google Slides
- Open Google Slides.
- The full interface — menus, toolbar labels, and dialogs — should now reflect your chosen language.
Note: This change applies across all Google Workspace apps (Docs, Sheets, Drive), not just Slides.
Method 2: Change the Spell Check Language in Google Slides
If you need to write content in a different language from your interface — for example, your interface is in English but your slides are in French — you can set the spell check language independently.
Step 1: Open Your Presentation
Launch Google Slides and open the presentation you’re working on.
Step 2: Access the Spell Check Language Setting
- Click “Tools” in the top menu bar.
- Hover over “Spelling” in the dropdown.
- Click “Spell check and grammar” or “Language” (the option label may vary slightly by region).
Step 3: Choose Your Spell Check Language
- Select the language that matches the content you’re writing.
- Google Slides will now underline errors based on that language’s dictionary.
This is especially useful when a single presentation contains slides written in more than one language — you can switch the active dictionary as needed while writing.
Method 3: Set Language for a Specific Text Block
For truly multilingual presentations — where different slides or even different paragraphs use different languages — Google Slides lets you set language at the text level. This keeps spell check accurate throughout.
Step 1: Select the Text
Highlight the specific text, text box, or paragraph you want to assign a language to.
Step 2: Assign the Language
- With the text selected, go to Tools in the top menu.
- Click “Spelling” → “Language.”
- Choose the language for that selected text block.
Practical tip: When pasting text from another source (e.g., a translated document), select all pasted text and reassign the spell check language immediately. This prevents a flood of false red underlines.
Tips for Working with Multilingual Google Slides Presentations
- Use consistent fonts that support extended character sets (e.g., Noto Sans covers hundreds of scripts including Arabic, Devanagari, and CJK characters).
- Right-to-left languages (Arabic, Hebrew, Urdu) require RTL text direction — composing in Google Docs first and pasting into Slides is a reliable workaround.
- Avoid hard-coding language-specific punctuation (like French guillemets « ») in templates that may be reused across languages.
- Test your presentation on a device set to the target language to catch rendering issues before presenting.

Frequently Asked Questions
1. How do I change the display language in Google Slides?
The display language is set through your Google Account, not inside Google Slides itself. Go to myaccount.google.com → Data & Privacy → Language, select your preferred language, and the change will apply across all Google Workspace apps including Slides.
2. Can I use different languages in the same Google Slides presentation?
Yes. You can switch the spell check language (Tools → Spelling → Language) while writing different sections. For best results, select the relevant text block and assign the correct language before typing.
3. How do I fix spell check flagging words incorrectly in Google Slides?
This usually means your spell check language doesn’t match the language you’re typing in. Go to Tools → Spelling → Language, select the correct language, and the dictionary will update immediately.
4. Does changing the Google Account language affect only Google Slides?
No — it affects all Google Workspace apps. If you only want to change the spell check language for a specific document or presentation, use the in-app Tools → Spelling → Language option instead.
5. Does Google Slides support right-to-left (RTL) languages like Arabic or Hebrew?
Google Slides has limited native RTL support. For complex RTL layouts, composing text in Google Docs (which has better RTL handling) and then copying into Slides is a common workaround. For official guidance, refer to Google Workspace support.
6. Will changing my language settings affect my existing presentations?
Changing the interface language won’t alter your slide content. However, changing the spell check language will update which words are flagged as errors from that point forward. Your existing text remains unchanged.
Conclusion
Getting language settings right in Google Slides takes only a few minutes but makes a real difference — cleaner spell check, better collaboration, and presentations that feel native to your audience’s language.
To recap: use Method 1 to change the full interface language, Method 2 to adjust spell check for your content language, and Method 3 for text-level language control in multilingual presentations.
