Newsletter Promo Image Size Guide

Useful image sizes for promoting newsletters, lead magnets, and email issues across social platforms.

If social is feeding your newsletter, your graphics need to sell the click quickly. A strong promo set usually includes a feed post, a Story cutdown, and a banner or thumbnail variation depending on channel.

Recommended sizes

• Instagram feed portrait: 1080 x 1350
• Instagram Story: 1080 x 1920
• LinkedIn banner: 1584 x 396
• Wide promo image: 1280 x 720

Keep the offer short, the value obvious, and the typography large enough to survive mobile previews.
