Use this interactive demo to learn how to set slide size before publishing your Google Slides presentation.

Quick summary

To increase slide size in Google Slides before publishing, open File > Share > Publish to web, switch to the Embed tab, select your preferred slide size from the dropdown, then click Publish. This lets you control the embedded presentation's display dimensions for a sharper, larger view on any webpage.

Steps

In your presentation, click File in the top-left menu, choose Share, then select Publish to web.
In the Publish to the web dialog box, click the Embed tab to access slide size settings.
Click the dropdown beside the Slide size option and select your preferred slide size (e.g., Large 1440x840).
Click Publish to make your presentation publicly available on the web at the chosen size.

📌 Why this matters

Controlling slide size in Google Slides before publishing ensures your embedded presentations display at the correct resolution on websites, blogs, and learning platforms. Many users embed presentations without adjusting dimensions, resulting in small, hard-to-read slides that reduce audience engagement. The Publish to web Embed tab gives you direct control over slide dimensions — from small to large — so your content looks sharp and professional at any screen size. This feature is essential for educators, marketers, and content creators who share Google Slides publicly via embed code.
