If you're getting started with your first website you probably don't know how much disk space an bandwidth you need.
If you're unsure of which plan is right for you just contact us giving us infos about your project, we will do our best to help you.
You might want to start with a SILVER1 account, and as soon as you need it you can upgrade to another plan, paying only the difference. Upgrading is easy, instantaneous and it comes without downtimes.
Usually a WordPress website uses from 400MB to 1000MB, so the SILVER 1 is optimal as it give you 2GB of disk space.
It's harder to make an estimate of the monthly bandwidth, since it depends from the kind of content you serve and the visits. None of our clients have ever had problems on SILVER accounts since the limits are really high, so you should now worry about this limit.
