1200×630 is a standard-definition resolution common in legacy displays, presentation projectors, and web content. While higher resolutions are now standard for displays, this size remains practical for email images, internal documents, and embedded web content where file size matters more than pixel-perfect detail.

At 0.8 megapixels, images at this resolution compress efficiently — typically under 150KB as JPEG at 85% quality. This makes it ideal for email newsletters, where many clients block images over 200KB or slow connections make large images impractical.

For presentations, this matches the native resolution of many older projectors and 4:3 aspect ratio displays. Exporting presentation images at this exact size prevents the projector from scaling and introducing blur.
