There is no one definitive answer to this question. The size of a blog depends on what you want your blog to achieve.
If you are just looking to have a fun hobby blog, then a smaller blog may be more suitable. However, if you are hoping to build a large following and generate revenue from your blog, then a larger blog may be more effective.
Some things to consider when determining the size of your blog include:
-How much content do you want to produce each month?
-Do you want your blog to be accessible from any device?
-How much time do you have to devote each month to blogging?
-What are your goals for your blog?
Based on these factors, it is generally recommended that a blog be between 500 and 1,000 words in length, and be accessible from any device. Additionally, it is recommended that bloggers spend at least 1 hour per week writing content, and that their goal is to generate at least 10 new followers per month.
