I have good news and bad news for you, with regard to this question.
The bad news first. Yes, your WordPress.com blog WILL eventually run out of space.
The good news: You get slightly over 3GB of space, and you can always get a space upgrade. Most people give up blogging before they have even used up a tiny fraction of that 3GB, so why are you worried?
Here’s my current status:
After close to FOUR years of blogging, and 565 blogposts uploaded, I have used just 32% of the free space allocated. Are you worried about running out of space? I’m not.
And here’s how much it costs for a space upgrade…
The following prices are per blog, per year:
- 10GB Space Upgrade: $20.00
- 25GB Space Upgrade: $50.00
- 50GB Space Upgrade: $90.00
- 100GB Space Upgrade: $160.00
- 200GB Space Upgrade: $290.00
