Tumblr Features

Most likely due to rapid growth and adoption, Tumblr leaves alot of its feature docmuentation hard to find, or not fully fleshed out.

Here is what I have found so far.

Uploading Media

When you upload media, Tumblr resizes it automatically into several discrete sizes - see below:

  • {Video-500} Embed-code for the content of a Video post. 500-pixels wide.
  • {Video-400} Embed-code for the content of a Video post. 400-pixels wide.
  • {Video-250} Embed-code for the content of a Video post. 250-pixels wide.
  • {PhotoURL-500} URL for the photo of a Photo post. No more than 500-pixels wide.
  • {PhotoURL-400}URL for the photo of a Photo post. No more than 400-pixels wide.
  • {PhotoURL-250} URL for the photo of a Photo post. No more than 250-pixels wide.
  • {PhotoURL-100} URL for the photo of a Photo post. No more than 100-pixels wide.
  • {PhotoURL-75sq} URL for a square version the photo of a Photo post. 75-pixels by 75-pixels.

The original file is discarded as far as I can tell. If you need a larger image, you must specify the custom width within the tag.

Ex. IMG src=”path/to/image” width=”692”

Note - your image may be subject to re-scaling degradation.
