Select 16:9 Widescreen for Modern Displays
Use the 16:9 aspect ratio as your default standard for most current monitors, TVs, and online meetings.
The 16:9 widescreen format has been the default standard since Office 2013. It perfectly fits modern laptops, HD displays, and remote conferencing software like Zoom or Microsoft Teams, preventing unsightly black bars from appearing on the sides of your slides.
Open your presentation and navigate to the 'Design' tab located on the top ribbon.
Look for the 'Slide Size' button, typically found on the far right side of the toolbar.
Click 'Slide Size' and select 'Widescreen (16:9)' from the drop-down menu.
Select 4:3 Standard for Legacy Equipment
Opt for the 4:3 aspect ratio only when you know you will be presenting on older projectors, iPads, or specific print materials.

Frequently Asked Questions
What happens if I change the slide size after designing my presentation?
Changing the aspect ratio after your slides are designed can cause images to stretch, text boxes to shift, and graphics to distort. You will likely need to manually adjust elements. When switching, presentation software usually asks if you want to 'Maximize' or 'Ensure Fit' to help manage the transition.
Which aspect ratio is best for Zoom or Microsoft Teams online meetings?
The 16:9 widescreen aspect ratio is highly recommended for online meetings. Most modern laptops, desktop monitors, and web conferencing platforms are optimized for widescreen displays, meaning 16:9 will fill the screen naturally without black borders.
How do I remove the black bars on the sides of my presentation?
Black bars (pillarboxing) appear when you display a 4:3 standard presentation on a 16:9 widescreen monitor. To fix this, change your slide size to 16:9 in the 'Design' tab. Be sure to review your slides afterward, as some elements may need repositioning.
Is 16:9 the same as 1920x1080 resolution?
Yes, 1920x1080 pixels (Full HD) uses a 16:9 aspect ratio. If you are designing slides that will be exported as video or displayed on standard HD or 4K screens, the 16:9 setting is the correct choice.
