PowerPoint slides are usually 16:9 widescreen , which is commonly 1920 x 1080 pixels for Full HD export, or 1280 x 720 pixels at a lower screen resolution. Older 4:3 standard slides are commonly 1024 x 768 pixels.

Quick Scoop

A PowerPoint slide does not have one fixed pixel size because the pixel dimensions depend on the slide ratio and export resolution. PowerPoint’s modern default is widescreen 16:9, while 4:3 is the older standard format.

Common sizes

  • 16:9 widescreen: 13.33 x 7.5 inches, often 1920 x 1080 pixels.
  • 4:3 standard: 10 x 7.5 inches, often 1024 x 768 pixels.
  • Custom sizes: PowerPoint can convert pixel dimensions you enter into its internal measurement units.

Practical rule

If you are making slides for modern screens, use 1920 x 1080 px as the safest default. If you are preparing for older projectors or a more square layout, 1024 x 768 px is the common 4:3 choice.

Tiny note

The exact pixel count can vary depending on how the file is exported or displayed, so the aspect ratio matters more than a single universal pixel number.
