GitHub在默认情况下是不显示仓库大小的，那如果我们要怎样才能查看一个仓库的大小？这里介绍几种方法，需要注意的是这里要区分公开仓库和私有仓库。
目录
一、GitHub自带查看仓库大小的功能（public、private）
三、利用浏览器插件：Enhanced GitHub（public、private）
一、GitHub自带查看仓库大小的功能（public、private）
因为这是自带功能，所以公开仓库和私有仓库都可以查看大小。
（以下内容转自：
如何查看自己的Github仓库占据了多少存储空间_汪子熙的博客-CSDN博客
）其实github上提供了非常方便的工具供我们查看。
登录github网页首页，选择自己账户的settings:
点击repository：
这里就有每个repository对应的存储空间大小：
二、利用GitHub提供的API查看（public）
只要访问指定网址，即可参看仓库大小，；所以只能访问公开仓库的信息。
语法：
https://api.github.com/repos/
user/repo ，
访问后得到一个包含仓库信息的json数据。
如，我的第一个仓库：
https://api.github.com/repos/yansheng836/hello-world
json数据如下：我们可以看到内容很丰富，其中的size就是仓库大小，单位是kb，其他内容有兴趣也可以了解下。

三、利用浏览器插件：Enhanced GitHub（public、private）
Google商店网址：
https://chrome.google.com/webstore/detail/enhanced-github/anlikcnbgdeidpacdbdljnabclhahhmd
下面是官方介绍：
概述
显示仓库大小，每个文件的大小，下载链接和复制文件内容的选项，
在GitHub网站顶部提供有用功能的扩展。
特征
1.显示仓库规模。
2.显示每个活动分支中的每个文件大小（不适用于文件夹/符号链接）
3.显示每个文件的下载链接（不适用于文件夹/符号链接）
4.直接将文件内容复制到剪贴板（对于markdown文件不起作用）
5.在查看文件内容的同时下载文件。
7.即将推出…请在https://github.com/softvar/enhanced-github/issues上打开一个问题以提出建议
注意：从v1.0.0开始-由于GitHub已停止直接下载文件，因此在按Alt / Cmd（对于Mac）/ Ctrl（对于Windows）时单击下载图标/按钮。
它是开源的-根据MIT许可证 https://github.com/softvar/enhanced-github
注意：私有仓库需要添加Token
该插件适用于公开和私有仓库，但是私有仓库需要添加token，不然因为权限不够，会访问不了。
添加token步骤：（详情可见：
GitHub – softvar/enhanced-github: Browser extension to display size of each file, download link and copy file contents directly to the clipboard
）
1. 先到
Sign in to GitHub · GitHub
，点击“Generate new token”，范围勾选repo就可以了(如下)，拉到最下面，点击“Generatetoken”申请一个token。
2. 复制token，然后（右键）点击该插件，选择“选项”，跳转后，等一会儿（10s左右），会弹出如下弹窗，将复制的token填进去，然后去访问一个自己的私有仓库就可以显示大小。
补充：该插件的另一个很棒的功能就是很简单就能下载一个文件（暂时不支持下载文件夹）
