Fastest Shopify Themes

Ranked by the real-world Core Web Vitals of the stores actually running each theme on mobile, not a lab test. The “few apps” column strips out heavy-app stores to show the theme’s own speed, apart from the merchant’s app-bloat.

Quick answer

We rank Shopify themes by the real-world Core Web Vitals of the stores actually running each one. Baseline ranks first, passing on 94.6% of its stores, among stores with enough traffic to appear in Chrome UX Report data. Showing 105 themes with real-world data.

Free vs paid

Free and paid themes look level until you compare like with like

Compared across stores running the same number of apps, 68.5% of stores on a free theme pass Google’s Core Web Vitals on mobile, against 70.1% of stores on a paid one, among stores with enough traffic to appear in Chrome UX Report data. That is 1.6 points faster on the paid themes. Put plainly: a small edge to the paid themes. The free side is 7,877 stores and the paid side 17,283, read across 8 app-load groups that held stores of both kinds.

Free themes

68.5%

matched on app load · 7,877 stores

Raw 68.5% across 7,877 stores, app load ignored

Paid themes

70.1%

matched on app load · 17,283 stores

Raw 68.7% across 17,283 stores, app load ignored

The two readings disagree, which is the finding. Set side by side with no account of app load, free and paid come out no real gap either way; hold the number of installed apps steady and the picture becomes 1.6 points faster on the paid themes. The raw figure is measuring the kind of store that buys a paid theme, not the theme.

How this is worked out: every store we hold real-user Core Web Vitals for is sorted by how many apps it runs, and free is compared against paid inside each of those groups, with the paid side re-weighted to the mix of groups the free stores sit in. A theme counts as free or paid on the price the Shopify Theme Store lists for it, and a theme whose price we do not hold is left out of both sides rather than guessed into one. Both matched percentages are worked out over the 7,073 free-theme stores the Chrome UX Report rates as passing or failing, which is the denominator they share. It draws on 24 free and 252 paid themes; the ranked lists below hold only the themes with enough stores of their own to be ranked one by one.

Real-world Chrome UX Report data on mobile, updated daily. This is an association between what a store runs and what its visitors measure, not a measurement of what a theme costs you in speed: nothing here is the same store tested twice. A figure needs at least 25 comparable stores behind it before we print it, and shows a dash below that. See the free themes ranked, the paid themes ranked, or how we measure.

How this data is collected: every number here is real-world Chrome UX Report data on mobile, the Core Web Vitals that actual Chrome phone users experienced, not a lab test. Themes are ranked by the share of their real stores that pass Google’s Core Web Vitals, adjusted for how many stores sit behind the figure. The Few apps column keeps the same stores but removes heavy-app ones, so the gap between it and All stores is the speed cost of merchant apps, measured per theme. Where a theme’s demo store gets enough real traffic to be in the Chrome UX Report, we show its own real-user number too.

Real-world Chrome UX Report data on mobile. All stores is the share of every real store running the theme that passes Google’s Core Web Vitals, among stores with enough traffic to appear in Chrome UX Report data; Few apps narrows to stores running 6 or fewer apps, so the gap is the speed cost of merchant apps. Each pass rate is shown with the number of stores behind it. Ranked by is that pass rate adjusted for how many stores back it, so a high rate on a handful of stores can’t outrank a solid one on thousands. Demo store is the theme’s own demo, shown where it has enough real traffic to be in the Chrome UX Report. Themes without at least 25 stores of real-world data are not ranked and are listed as pending; a number below that floor is shown as a dash rather than a figure.

Frequently asked questions

What is the fastest Shopify theme?

Baseline ranks first, passing on 94.6% of the real stores running it, among stores with enough traffic to appear in Chrome UX Report data. The order accounts for how many stores sit behind each figure, so a theme with a slightly higher percentage measured across far fewer stores can still rank below it. We rank 105 themes by the real-world speed of the stores actually using each one, not by a lab test.

Do paid Shopify themes load faster than free ones?

A small edge to the paid themes. Compared across stores running the same number of apps, 68.5% of stores on a free theme pass Google's Core Web Vitals on mobile against 70.1% of stores on a paid one, among stores with enough traffic to appear in Chrome UX Report data. That is 1.6 points faster on the paid themes, read across 7,877 free-theme stores and 17,283 paid-theme ones. Set side by side with no account of app load the same stores read no real gap either way, which is a difference between the stores that buy paid themes rather than between the themes.

How is Shopify theme speed measured?

By real-world Core Web Vitals from Google's Chrome UX Report, across the stores actually running each theme. A theme is ranked by the share of those stores that pass all three Core Web Vitals, adjusted for how many stores sit behind the figure. The "few apps" view narrows that to stores running few apps, isolating the theme's own speed from merchant app-bloat.

Why do some themes show no real-world speed data?

Our data comes from real stores in the Chrome UX Report, and a theme needs enough of its stores there before we can measure it. Newer or less common themes show pending until enough of their stores are seen, so the ranking covers the themes with real-world data rather than every theme.

Does a faster theme mean a faster store?

It is a strong starting point, not a guarantee. A theme with a high pass rate tends to be well built, but your own store's speed also depends on your images, apps, and custom code. The "few apps" view shows how the theme does once heavy-app stores are set aside.

How often is the speed data updated?

Daily. The figures refresh as new Chrome UX Report data comes in each day.

How this data works

Every number on this page is real-world data from Google's Chrome UX Report, measured on mobile phones: the Core Web Vitals that actual Chrome users experienced on real stores. There is no lab test in the ranking. A theme is ranked by the share of the real stores running it that pass all three Core Web Vitals (loading, responsiveness, and visual stability), adjusted for how many stores sit behind the figure. Reporting a single form factor keeps it comparable row to row, and mobile is where most storefront traffic and the tighter thresholds live.

The "few apps" column is the number no one else can produce. It keeps the same real stores but narrows to those running 6 or fewer apps, so the gap between it and "all stores" is the speed cost of merchant app-bloat, isolated per theme. Because both halves come from the same set of stores, that within-theme comparison holds up even though the overall sample leans toward themes people look up more often.

Where a theme's demo store gets enough real traffic to appear in the Chrome UX Report, we show its own real-user number too, so you can compare the theme as its developer built it against how it performs in merchants' hands. Most demo stores are too low-traffic for this, so that column appears only for the popular ones.

How we rank, and why thin samples do not win: the order accounts for how many stores sit behind each number, not just the raw percentage. A theme passing 92% across 24 stores is measured with far less certainty than one passing 76% across 48,000, so a small sample is held to a more cautious figure and the theme with more data behind it ranks higher. We would rather rank a theme where the number is solid than crown one on a handful of stores. The percentage you see is still the real pass rate; the ordering just reflects how much data supports it.

Coverage limits, stated plainly: a theme needs at least 25 of its stores in the Chrome UX Report before we rank it, so newer or less common themes are left out until then. A store only enters the Chrome UX Report once it has real traffic of its own, which means the stores behind every figure here skew larger than the average Shopify store: the pass rates are what those stores experienced, not what all Shopify stores experience. The comparison between rows still holds, because every row is drawn the same way. The other safeguard is the ranking itself: because we sort by the confidence-adjusted score, a theme measured on a few dozen stores is held to a cautious figure and cannot leapfrog one measured on thousands. The field data also covers every version of a theme still in use, so a theme spanning several major releases is partly measuring its own history, not only its current version.

Independent by design: rankings are determined solely by live detection data. Affiliate relationships never affect what ranks or how stores are counted. Read the full methodology →
