Tumblr image sizes overview
Tumblr displays content differently depending on theme settings, dashboard view, and device type. While Tumblr supports multiple image dimensions, using recommended sizes helps maintain clarity and prevents unexpected resizing.
Because Tumblr automatically adjusts large images, designing at optimal widths ensures posts remain sharp without distortion or compression artifacts.
Post image (recommended width)
Recommended vs supported sizes
Tumblr post images are best uploaded at 1280 pixels wide, with height scaling proportionally.
Best practices for feed visibility
Keep key visuals centered and avoid placing important text near the edges, as different themes may crop or resize content.
Quality and export considerations
Export images at 1280 px width to reduce automatic resizing and preserve clarity.
Vertical post image
Recommended vs supported sizes
Vertical posts commonly use 1280 × 1920 pixels, ideal for tall visuals.
Best practices for feed visibility
Ensure essential content remains within the upper portion of the image, as dashboard previews may truncate longer posts.
Quality and export considerations
Avoid excessively tall images that may be compressed or partially hidden in previews.
Header image
Recommended vs supported sizes
Tumblr header images are designed at 3000 × 1055 pixels, providing wide coverage across themes.
Best practices for feed visibility
Keep logos and text centered horizontally. Some themes crop header edges depending on screen size.
Quality and export considerations
Export at full resolution to maintain sharpness on large displays.
Profile picture
Recommended vs supported sizes
Profile pictures use 128 × 128 pixels and appear as small square or circular images depending on theme.
Best practices for feed visibility
Center logos or faces and avoid small text due to limited display size.
Quality and export considerations
Use high-contrast visuals to maintain clarity at small scale.
Background image
Recommended vs supported sizes
Background images are best designed at 1920 × 1080 pixels.
Best practices for feed visibility
Keep patterns subtle and avoid placing key information in background areas that may be obscured by content.
Quality and export considerations
Export at exact dimensions and high quality to prevent blurriness.
