WordPress has modest technical requirements that almost every modern host meets: a recent version of PHP, a MySQL or MariaDB database, and HTTPS support via a free SSL certificate. You rarely have to think about these because good hosts provide them by default — but understanding them helps you confirm a host can run WordPress well and keep it fast and secure.

This guide explains WordPress’s hosting requirements in plain language: what PHP, MySQL, and the other pieces are, what versions to look for, and why they matter for speed and security.

The core requirements

WordPress needs three main things from a host: PHP (the programming language WordPress is written in), a database (MySQL or the compatible MariaDB) to store its content and settings, and HTTPS support so the site can run securely over SSL.

That is essentially it. WordPress is designed to run widely, so its requirements are light and met by virtually every modern host. When a host advertises WordPress support or a one-click installer, it already meets these requirements.

PHP: the language WordPress runs on

PHP is the programming language that powers WordPress, and its version matters for both speed and security. WordPress recommends a current, supported version of PHP, because newer versions run faster and receive security updates, while old versions are slower and can be vulnerable.

Good hosts run a recent PHP version by default and let you choose the version in your control panel. If you ever see a warning in your WordPress dashboard about an outdated PHP version, updating it (or asking your host to) is a simple, worthwhile speed and security boost.

The database: MySQL or MariaDB

WordPress stores its content, settings, and user data in a database, using MySQL or its drop-in compatible alternative MariaDB. Every WordPress site needs one database, which is created automatically during a one-click install.

You rarely interact with the database directly — WordPress and your host manage it — but it is why hosting plans mention a number of databases they allow. Each WordPress install needs one, so that limit caps how many WordPress sites you can run on a plan.

The requirements at a glance

Here is what WordPress needs from a host, and what to look for.

Requirements that affect speed and security

Beyond the bare minimums, a few things strongly affect how well WordPress runs. A current PHP version and enough PHP memory keep the site fast and let plugins work; fast NVMe storage speeds up database and file access; and caching (server-level or via a plugin) dramatically improves load times.

On the security side, HTTPS via SSL is essential and free, and keeping PHP and WordPress current closes vulnerabilities. So while WordPress technically runs on the minimums, meeting the recommended versions and adding caching is what makes it run genuinely well.

Do you need to worry about this?

For most people, no. A good modern host meets and exceeds WordPress’s requirements by default, runs a current PHP version, provides the database and free SSL automatically, and handles the technical side for you. You simply install WordPress and start building.

Understanding the requirements is mainly useful for confirming a host is up to date and for troubleshooting the occasional warning. Choose a reputable host with a one-click WordPress installer, and the requirements take care of themselves.

FAQs

What are the requirements to run WordPress?

WordPress needs a current version of PHP (the language it runs on), a MySQL or MariaDB database to store content, and HTTPS support via a free SSL certificate. These are light requirements met by virtually every modern host, especially those offering a one-click WordPress installer.

What PHP version does WordPress need?

WordPress recommends a current, supported version of PHP, because newer versions are faster and receive security updates while old ones are slower and can be vulnerable. Good hosts run a recent version by default and let you choose it in your control panel.

Does WordPress need a database?

Yes. WordPress stores its content, settings, and user data in a MySQL or MariaDB database, and each WordPress install needs one. It is created automatically during a one-click install, so you rarely interact with it directly.

Do I need SSL to run WordPress?

You do not strictly need SSL for WordPress to function, but you absolutely should use it. HTTPS via a free SSL certificate secures your site, is expected by visitors and browsers, and helps SEO. Good hosts provide SSL free, so there is no reason not to enable it.

How much memory does WordPress need?

WordPress runs on modest memory, but more helps if you use many or heavy plugins. Good hosts allocate enough by default. If you see a memory-limit warning in your dashboard, your host can usually raise the PHP memory limit, or you can move to a plan with more resources.

Do I need to worry about WordPress requirements?

Usually not. A good modern host meets and exceeds WordPress’s requirements by default — current PHP, a database, and free SSL — and handles the technical side for you. Understanding them is mainly useful for confirming a host is current and troubleshooting occasional warnings.

The bottom line

WordPress’s hosting requirements are light: a current PHP version, a MySQL or MariaDB database, and HTTPS via free SSL. Almost every modern host meets them by default, which is why you rarely have to think about them when choosing WordPress hosting.

Where the requirements matter is quality: a current PHP version, fast NVMe storage, enough memory, and caching are what make WordPress run genuinely fast and securely, not just function. Choose a reputable host with a one-click installer, keep PHP and WordPress current, and the requirements look after themselves.
