Limits on Blogger
We try to give you a lot of room to play here on Blogger, so you'll see that a lot of the important "limits" here aren't really very limiting. But just in case you were wondering, here is some information about what a single Blogger account will hold.
Number of Blogs: You can have up to 100 blogs per account.
Number of Posts: There is no limit on the number of posts you can have on one blog. They will all be saved on your account (unless you manually delete them) regardless of whether you are publishing archives or not.
Number of Pages: There is no limit on the number of pages you can have on one blog.
Size of Posts: Individual posts do not have a specific size limit, but very large posts may run you up against the page size limit. (See the next item.)
Size of Pages: Individual pages (the main page of your blog, or your archive pages) are limited to 1 MB in size. This will allow for a few hundred pages of text, but it may be a problem if you are listing hundreds of posts on the front page of your blog. If you hit this limit, you will see an error message saying "006 Please contact Blogger Support." You can get around this error by lowering the number of posts on your main page, which will have the added benefit of making your page load faster as well.
Number of Comments: A post can have any number of comments. As with archived posts, if you choose to hide comments on your blog, all pre-existing comments will remain saved on your account.
Number of Pictures: Up to 1 GB of total storage, shared with Picasa Web. If you've upgraded to Google+, your photos will be stored in Google+ Photos, where you have 15GB of storage space shared with Gmail and Drive.
Size of Pictures: If you are posting pictures through Blogger Mobile there is a limit of 250K per picture.
Team Members: There is a limit of 100 members per blog.
Number of Labels: Up to 2000 unique labels per blog and 20 per post.
Blog Description: Limited to 500 characters, with no HTML. Adding additional characters or HTML may cause it to revert to a previous setting.
"About Me" Profile Information: Maximum of 1,200 characters.
Profile Interests and Favorites: Maximum of 2,000 characters in each field.
Importing blogs: there are no file size limits for importing blog. Limits for number of imports in a day may apply.
Note: Users of the discontinued BlogSpot Plus service have a slightly different set up. Since these accounts included full FTP access, they were limited to either 25 MB or 100 MB, depending on which type of upgrade they had. In these cases, if you fill up your allotted space with images or other files, then you may not be able to upload new posts. To get around this, you will need to remove unused files from the account in order to free up more space.
