The Complete Guide to LinkedIn Ad Sizes and Specs
Running B2B campaigns on LinkedIn without the right creative dimensions is an expensive guessing game. Upload a graphic that’s a few pixels too small, and LinkedIn will stretch it into a blurry mess. Miss the aspect ratio mark, and your carefully crafted text overlay gets abruptly cropped right in the middle of a vital data point.
Because professional buyers scroll with a critical eye, your ads need to look native, crisp, and intentional. This comprehensive guide breaks down the exact dimensions, file sizes, and best practices for every major LinkedIn ad format.
1. Single Image Ads
Single image ads remain the backbone of B2B lead generation. They appear directly in the user’s feed alongside organic posts, meaning your visual needs to stop the scroll instantly.
- Landscape (1.91:1):
- Recommended Size: $1200 times 628$ px
- Delivery: Appears on both desktop and mobile feeds. Great for standard landscape imagery, website link previews, and data charts.
- Square (1:1):
- Recommended Size: $1200 times 1200$ px
- Delivery: Desktop and mobile feeds. Provides more vertical real estate than landscape, perfect for quotes or product headshots.
- Vertical / Portrait (4:5):
- Recommended Size: $720 times 900$ px (or up to $1080 times 1350$ px)
- Delivery: Mobile-only. This format dominates mobile screen real estate, yielding higher engagement rates.
- Technical Constraints: Formats accepted include JPG, PNG, or non-animated GIF, with a maximum file size of 5 MB.
2. Video Ads
B2B buyers love video content, but LinkedIn’s professional audience has zero patience for low-resolution or awkwardly cropped footage.
