How to Resize Image for Microsoft Teams Background

Microsoft Teams' virtual background feature is widely used in UK and US workplaces to maintain privacy or keep meetings looking polished. Uploading a correctly sized image ensures the background looks crisp without any stretching or pixelation — especially important when you're presenting to clients or leadership.

Microsoft Teams Background Image Size

Teams recommends background images at 1920×1080 pixels with a 16:9 aspect ratio. If your image is smaller, Teams will upscale it, which causes blurring. For ultra-wide monitors, 3840×2160px (4K) is ideal. Teams accepts PNG, JPG, and BMP formats.

How to Set a Custom Teams Background

1. Resize your image to 1920×1080px using the Image Resizer at imgresizr.com.
2. Save it as a JPG or PNG file.
3. Open Microsoft Teams and start or join a meeting.
4. Click the three-dot menu (···) → Video Effects → Background.
5. Click Add new and upload your resized image.
6. Select it from the background gallery and click Apply.

Tips for a Professional Teams Background

Use Branded Backgrounds for Client Calls

Many UK and US businesses create branded Teams backgrounds with their company logo, brand colours, and a clean layout. This is a subtle but effective way to reinforce professionalism during video calls without a word being said.

Avoid Fine Details at the Edges

Teams' AI background removal isn't perfect — it can sometimes create a fuzzy edge around your silhouette. Keep important text and logos in the central area of your background image to ensure they're always visible.
