I want to view the total repo size of a project hosted on GitHub without having to clone it. Sometimes I do this:

  1. Start cloning some GitHub repository

    Receiving objects: 45% (218/476), 5.50 MiB | 27 KiB/s

    Already drained 5MB? Suspend...

  2. Clone the repository on a server with a normal internet connection just to see its size.

  3. Continue (or abort) the local cloning.

How do I find out the repository size in advance? In the search I see repository size, but not in other places.


Using Github API:

$ echo https://github.com/hlamer/enki.git | perl -ne 'print $1 if m!([^/]+/[^/]+?)(?:\.git)?$!' | xargs -i curl -s -k https://api.github.com/repos/'{}' | grep size
"size": 284,
  • On mac, there's no -i parameter for xargs, so it's: $ echo https://github.com/hlamer/enki.git | perl -ne 'print $1 if m!([^/]+/[^/]+?)(?:\.git)?$!' | xargs -I{} curl -s -k https://api.github.com/repos/'{}' | grep size – Daniel Golden Aug 11 '15 at 20:25
  • and that is size in... kilobytes? – capybaralet Apr 7 '16 at 3:50

In Firefox you can use the GitHub Repository Size add-on.

  • Why the downvote? Does the extension or userscript fails to work or contains malware? – Vi0 Jan 13 '18 at 19:12
  • No, everything works just fine... – vstepaniuk Jan 13 '18 at 23:51

Use Google Chrome browser and install this extension

Adds the repo size to the home page:

GitHub Repo Size extension screenshot

curl \
-H "Accept: application/vnd.github.v3+json" \
-s https://api.github.com/repos/torvalds/linux | \
jq '.size' | \
numfmt --to=iec --from-unit=1024


  1. fetch repo info from github api using curl

We get a json response like this:

  "id": 2325298,
  "node_id": "MDEwOlJlcG9zaXRvcnkyMzI1Mjk4",
  "name": "linux",
  "full_name": "torvalds/linux",
  "private": false,
  "size": 3018913,  <<<This is what we need
  "stargazers_count": 99224,
  "watchers_count": 99224,

  1. Pipe the json response to jq parser and find the required attribute-value pair.

    . indicates the root of the json body and size is the required attribute from the root body

Output (the size in kB):

  1. Then pipe the output to numfmt
$ man numfmt

     iec    1K = 1024, 1M = 1048576, ...

     specify the input unit size (instead of the default 1)
     (it basically tells that the input is in kB(1024B) insted of B



For private repos pass a token as a header

-H "Authorization: token GITHUB_TOKEN"

replace GITHUB_TOKEN with a github token that has access to private repos

    Can you explain what this command does? How does it help in this situation? Thanks – codingbadger Oct 13 '20 at 6:48
  • It fetches repository metadata using curl, then extracts "size" field from it using jq, then converts raw bytes to human-readable filesize with numfmt. – Vi0 Oct 14 '20 at 21:59

One can achieve this using one's browser console and running

  .then(v => v.json()).then((function(v){
   console.log(v['size'] + "KB")

Let's consider a practical example.

Assuming one wants to find the size of this repo using Firefox.

Open the console with Ctrl+Shift+K.

Then paste the following code

  .then(v => v.json()).then((function(v){
   console.log(v['size'] + "KB")

Press enter and one will receive the size of the repo as one can see in the image bellow.
