When and Why to Use the 1200x628 Dimension
The 1200x628 pixel dimension is the standard image size for Facebook link preview ads and event cover images. It uses a 1.91:1 aspect ratio — nearly identical to the Open Graph standard of 1200x630, but the two-pixel height difference reflects Facebook's specific ad template requirements. If you run Facebook or Instagram ads with a link destination, 1200x628 is the dimension Facebook's ad platform expects for landscape single-image formats.
The distinction between 1200x628 and 1200x630 is subtle but real. Facebook's ad manager documentation specifies 1200x628 for link ads, while the Open Graph specification (used for organic link previews on Facebook, LinkedIn, Slack, and other platforms) calls for 1200x630. In practice, the two-pixel difference is invisible to users. However, if you are producing hundreds of ad creatives through an automated pipeline, using the exact spec dimension avoids any sub-pixel rounding that could shift your composition.
Marketers running Facebook and Instagram ad campaigns use 1200x628 as their default landscape creative size. This format displays as a wide card beneath the ad text, with a headline and call-to-action button below the image. The wide aspect ratio gives you space for product photography, lifestyle shots, or promotional graphics without the image feeling vertically cramped. It works especially well for e-commerce product showcases, real estate listings, travel promotions, and any ad where horizontal composition tells a better story than a square crop.
Beyond paid ads, 1200x628 is used for Facebook event cover images. When you create a Facebook event, the cover image displays at this dimension on desktop. On mobile, it gets cropped to approximately 16:9, which shaves a few pixels from the sides. Keep your event title and key visual elements in the center 1080x560 area to guarantee they survive both desktop and mobile rendering.
This dimension also works as a general-purpose Open Graph image. Because the two-pixel height difference from 1200x630 is imperceptible, a 1200x628 image functions correctly as an `og:image` for website link previews. If you maintain a library of promotional images for both paid ads and organic sharing, standardizing on 1200x628 means one image works for both purposes without re-exporting.
1200x628 vs Similar Social/Ad Dimensions
| Dimension | Aspect Ratio | Common Use | File Size (JPEG, q85) | Best For |
|---|---|---|---|---|
| 1200x628 | 1.91:1 | Facebook link ads, event covers, OG images | 100-220KB | Paid social advertising, Facebook event banners |
| 1200x630 | 1.91:1 | Universal Open Graph image standard | 100-220KB | Website link previews, organic social sharing |
| 1200x675 | 16:9 (1.78:1) | Twitter/X cards, YouTube thumbnails | 110-230KB | Twitter link cards, video thumbnails |
| 1080x566 | 1.91:1 | Facebook ad render size (in-feed display) | 70-160KB | Exact-pixel ad mockups for feed preview |

Notes: Choose 1200x628 when creating Facebook ad creatives or event covers. For organic link sharing across all platforms, 1200x630 is the safer default. The visual difference between the two is undetectable — the choice comes down to which spec you are optimizing for.
Frequently Asked Questions
What is the difference between 1200x628 and 1200x630?
Two pixels of height. 1200x628 is Facebook's ad-specific dimension for link ads and event covers. 1200x630 is the Open Graph specification used for link preview images across all platforms. Both produce a 1.91:1 aspect ratio and are visually identical. If you only need one size, 1200x630 has broader compatibility, but 1200x628 is pixel-accurate for Facebook's ad templates. Resize to either dimension in one step.
Can I use 1200x628 as my website's OG image?
Yes. The two-pixel height difference from the standard 1200x630 OG dimension has no visible effect on any platform. Facebook, LinkedIn, Slack, Discord, and iMessage all render 1200x628 correctly as a large-format link preview card. If you are already producing 1200x628 images for Facebook ads, you can reuse them as OG images without re-exporting. Read more about optimizing images for SEO including OG tag best practices.
What file format should I use for Facebook ads at 1200x628?
JPEG at quality 85-90 is the standard choice. Facebook re-encodes every image, so starting with high-quality JPEG minimizes double-compression artifacts. For ad creatives with sharp text overlays or brand logos, PNG may preserve edges better — Facebook sometimes keeps the PNG encoding when it determines the file is already compact. After resizing, compress the image to keep upload times fast without sacrificing visual quality.
How does a 1200x628 image display on Instagram?
Instagram uses Facebook's ad system, so 1200x628 landscape ads appear on Instagram feeds. However, Instagram's feed favors square (1:1) and portrait (4:5) formats — a 1.91:1 landscape image gets less vertical screen space in the feed, which can reduce engagement. If Instagram is a primary placement, consider creating a separate 1080x1080 or 1080x1350 version alongside your 1200x628 Facebook creative. Use the resize for Facebook tool for all Facebook-specific sizes.
Will my 1200x628 event cover get cropped on mobile?
Yes. Facebook crops event covers on mobile to approximately 16:9, which is slightly narrower than the 1.91:1 desktop display. The crop removes a thin strip from the left and right edges. Keep text and important visual elements within the center 1080x560 pixels to ensure nothing critical is lost. Preview the event on a mobile device before publishing. The Facebook image size guide covers all event image specifics.
Should I design at 1200x628 or at a larger size and downscale?
Design at exactly 1200x628. Designing larger and downscaling introduces an extra resampling step that can soften text and fine details. Facebook applies its own downscaling and re-encoding on upload, so giving it a pixel-accurate source at the target dimension produces the sharpest result. Use the resize tool to hit the exact dimension, then export as JPEG q85-90.
How It Works
Drag and drop any image — JPEG, PNG, WebP, AVIF, and more are all supported.
The tool pre-fills the target dimensions (1200×628 pixels). Choose fit mode: contain (preserve ratio), cover (fill and crop), or stretch (exact dimensions).
Your resized image is ready. Optionally compress or convert the format before downloading.
