For the best results, use an image that is 580 x 362 pixels.
This is the recommended size for all Alignable sponsorship ad images. Using this exact size ensures your image displays clearly and is not cropped, stretched, or distorted when members view your ad.
Quick reference:
Width: 580 pixels
Height: 362 pixels
Aspect ratio: approximately 8:4.5 (roughly 16:9 landscape)
Tips for your ad image:
Upload a high quality, horizontal image at 580 x 362 pixels for the cleanest display. Images that are too small may appear blurry, and images with different proportions may be cropped automatically. Refresh your image every two to three weeks to keep your ad looking fresh to members who have already seen it.
