Size for peaks

We assume 10% of daily traffic arrives in the busiest hour, then add 30% headroom.

RAM

Usually the limit

PHP-FPM workers, MySQL buffers and Node processes run out of memory long before CPU.

NVMe

Fast disks help

NVMe storage cuts database query times — often worth more than an extra core.

Server Sizing Calculator — FAQ

How much RAM does a WordPress site need?+
A typical WordPress site with caching runs well on 2 GB. WooCommerce stores and sites with 5,000+ daily visitors usually need 4 GB or more.
Is this estimate exact?+
No — it is a planning estimate based on typical workloads. Heavy plugins, uncached pages or large databases need more. Start here, then scale up — VPS upgrades take minutes.
Shared hosting or VPS?+
Under ~2,000 daily visitors on a cached site, cloud hosting is usually enough. Above that, or for custom apps, a VPS gives guaranteed resources.
