Two themes look equally good in their screenshots. One has a polished sales page and a long feature list; the other is plainer but comes up in every forum thread you read. You will live with whichever you pick for years, through updates, new staff and the next redesign, so the screenshot is the least useful thing to judge by.
Most of what tells you how to check the quality of a WordPress theme is public and takes under an hour to read. It is in the theme’s update history, its support forum, its documentation and how its demo behaves on an ordinary phone. This guide goes through each one, with what a good sign and a warning sign look like, so you can choose a good theme without reading any code.
Start with what you actually need
Quality only means something against a purpose. Before comparing themes, write down in a few lines what the site has to do: the pages you need, whether you sell online, whether you want to edit layouts yourself, and whether you plan to use the block editor or a page builder. A theme that is excellent for an online shop can be a poor fit for a five-page service business, and the other way round.
It also helps to know whether you want a block theme, edited through the Site Editor, or a classic theme, edited through the Customizer. Our overview of block themes and classic themes explains the difference in plain words.
How to check the quality of a WordPress theme: the public signals
These are the signals worth reading for any theme, free or paid. For themes in the wordpress.org directory, most of them appear on the theme’s page there. For commercial themes, look on the seller’s site, changelog and marketplace listing.
| Signal | Where to look | Good sign | Warning sign |
|---|---|---|---|
| Update history | “Last updated” date, changelog | Regular updates, including ones that mention new WordPress versions | No update in a long time, or a changelog that stops suddenly |
| Support | Support forum or ticket system | Recent questions answered by the theme’s own team | Unanswered threads, or replies only from other users |
| Reviews | Ratings and written reviews | Specific comments about support and updates | Recent complaints about broken updates or abandoned features |
| Requirements | Required WordPress and PHP versions | Works on current versions | Asks for an old PHP version |
| Documentation | Help pages linked from the theme | Clear guides for the basic setup tasks | None, or only video promos |
| Accessibility | “Accessibility Ready” tag on wordpress.org | Tag present, or a clear accessibility statement | No mention at all |
Update history
This is the single most useful signal. A theme that is updated regularly is being looked after: bugs get fixed, security problems get closed, and it keeps working as WordPress changes. Open the changelog and read the last few entries. Entries that mention compatibility with a recent WordPress release, fixes reported by users, and security fixes are what you want to see.
A long silence is a warning, even if the theme looks fine today. A theme that stops being updated slowly becomes a problem, and swapping it later is real work.
The support forum
Read the support threads from the last few months, not the ratings. Look at what people ask about and who answers. A theme whose developers reply politely and specifically, even when the answer is “that needs custom work”, is a theme you can rely on. A forum full of repeated questions about the same bug with no reply tells you what your own support experience would be.
Reviews
Skim the low ratings first. A few angry reviews are normal for any popular theme. What matters is the pattern: if several recent reviews mention the same broken update or a feature that disappeared behind a paid upgrade, take it seriously. Five-star reviews that only say “great theme” tell you little.
Test the demo the way a customer would
A demo is a sales tool, but it still shows you how the theme behaves. Open it on your own phone, not just a desktop browser, and try these:
- Open the menu. Does the mobile menu open and close easily? Can you reach every page with your thumb?
- Read a long page. Is body text a comfortable size without zooming? Do headings stand out clearly?
- Tap the buttons. Are they big enough and far enough apart that you hit the right one?
- Try a form. Can you fill it in on a phone without fields being cut off?
- Use the keyboard on a computer. Press Tab repeatedly. You should see a visible outline moving from link to link. If focus disappears, people who navigate by keyboard will struggle.
- Look at a blog post page and an archive page, not just the home page. These are the templates your site will use most.
Speed is a separate question with its own tests. Our guide to picking a theme that stays fast covers it, including why a demo’s own speed score can mislead.
Check how much the theme holds onto
A good theme controls design. A risky one also holds your content. Watch for:
- Content stored by the theme. If testimonials, portfolios or team members can only be added through the theme’s own panel or companion plugin, they may disappear or need rebuilding when you change themes later.
- Theme shortcodes. Buttons, columns or boxes added with the theme’s own shortcodes turn into bracketed text if the theme is ever switched off.
- A long list of required plugins. Each one is something else to update and keep licensed.
- A bundled page builder you did not plan to use. Your pages will depend on it for as long as the design lasts.
Ask yourself one question: if I changed theme in three years, what would I have to rebuild? The less, the better.
Check where the theme comes from
Download a theme only from the wordpress.org directory, the developer’s own site or a well-known marketplace where the developer sells it. Themes in the wordpress.org directory go through a review before they are listed. A “free download” of a premium theme from anywhere else is usually a nulled copy, and those regularly carry hidden code. Our article on why nulled themes carry malware explains the risk.
For commercial themes, also check what the licence includes: how long updates and support last, and what happens when that period ends. Our comparison of free and premium themes goes into those trade-offs.
A shortcut: see what similar businesses use
If you admire a competitor’s site, or a business in another city, our free WordPress theme detector can often tell you which theme it runs. That gives you a real, working site to look at rather than a demo. Remember that the site’s look may owe as much to its designer as to the theme, so run the same checks above before deciding.
Try it before you commit
The last check is to install the theme on a staging copy or a test site and spend an hour with it. Change the logo, set your colours, build one page and edit the header. You will learn more about whether the theme suits you from that hour than from any sales page. If it feels like a fight now, it will feel like a fight every time you make a change.
Choosing a theme is one of the longer-lasting decisions in our guide to managing your WordPress site, so it is worth the hour.
Frequently asked questions
How often should a good WordPress theme be updated?
There is no fixed number, but a well-maintained theme usually has several updates a year, often including one soon after a major WordPress release. What matters more is that updates keep coming and the changelog explains them. A theme with no updates for a year or more deserves a closer look before you trust it.
Does a high number of active installs mean a theme is good?
It means many people use it, which usually brings more testing, more answers online and less risk of abandonment. It does not prove the theme suits your site. A popular multipurpose theme can still be heavier or more complicated than you need, so use it as one signal among the others, not the deciding one.
Can I check the quality of a theme I already have installed?
Yes. Look at Appearance, Themes for the version number and compare it with the latest one on the theme’s page or changelog. Check when it was last updated, read recent support threads, and test your own site on a phone. If the theme is far behind or no longer updated, start planning a change.
What does Accessibility Ready mean on a WordPress theme?
It is a tag on the wordpress.org theme directory for themes that have passed an extra accessibility review, covering things like keyboard navigation, visible focus, headings and colour contrast. It gives you a sound starting point. Your own content still matters, such as alt text, clear link wording and readable colours.
If you would like a second opinion on a theme before you commit, or on the one your site already runs, our WordPress support team can look it over with you and explain what we find.
