Blogger is free, so it has some limits but most of us will never reach those limits. Check below list for limits:
- Number of Blogs: maximum is 100 blogs for each account.
- Number of Team Members: maximum is 100 members for each blog.
- Number of Labels: maximum 2000 / 1 blog and 20 / 1 post.
- Size of Pages: maximum 1 MB HTML code.
- Size of Image: maximum 250K per image (limits for mobile only, unlimited with desktop)
- Size of Image Hosting: maximum 1GB per account, but can increase when you link Blogger with G+.
- Blog Description Length: maximum 500 characters, raw text, not HTML.
- “About Me” Description Length: Maximum 1200 characters
- “Profile Interests and Favorites” Length: 2000 characters each field.
Have no any limit for Number of Posts / Pages / Comments. Also have no limit for Number of Image, you just upload any images until you reach the size of Image Hosting. There is no limit for size of post too.
Even if you reach the limits, Google still has option for you to pay to get premium service which allow you do almost thing unlimited.
So I think that limitation is nothing, the thing you need to worry about is limits of your ideas for blog content.
