Twitter Card Image Requirements
The twitter:image meta tag needs a raster PNG or JPG — X's card renderer doesn't support SVG. Design your card layout in SVG to keep logos and text crisp, then export at the recommended size.
- twitter:image needs PNG/JPG, not SVG
- Summary cards: ~1:1; large image cards: ~2:1
- Design crisp logos and text in SVG first
Reusing the Same Design for OG
Many sites use the same SVG template for both Open Graph and Twitter card images, just adjusting crop ratios, since both ultimately export to raster.
- Share one SVG template for OG and Twitter cards
- Adjust aspect ratio per platform requirement
- Export both as raster from the same source
Frequently Asked Questions
What aspect ratio should a Twitter large image card use?
Use roughly a 2:1 aspect ratio (commonly 1200x600) for summary_large_image cards, exported as PNG or JPG.
Can I use the same SVG for both OG and Twitter images?
Yes — design once in SVG and export two raster crops/sizes, one for og:image and one for twitter:image.
