Presentation Responsive Tester
The deck that fits your laptop is not the deck the projector shows. See the same slide at six sizes at once, with the layout problems each one causes.

How to Use
- Load the presentation.
- Pick a slide with the arrows — every device is re-rendered at that slide.
- Look at the note under each preview: it tells you how far the content overflows at that size.
FAQ
Which sizes are tested?
Projector and PowerPoint 16:9 (1280 × 720), Full HD (1920 × 1080), the older 4:3 (1024 × 768), a 16:10 laptop (1440 × 900), a tablet in landscape (1024 × 768 at tablet width) and a phone (390 × 844).
Why does it matter if my deck is 16:9?
Because the room decides, not you. Meeting-room screens and PowerPoint use 16:9, many older projectors are 4:3, and people open decks on phones. A layout in vh units or with a fixed pixel height breaks the moment the shape changes.
It says content overflows but I cannot see it.
The overflow is hidden by the slide’s own overflow rule — it is there, just clipped. That is exactly what gets lost when you present or export.
Is my presentation uploaded anywhere?
No. Every size is rendered locally in a sandboxed frame.
