What is the fastest Shopify theme in 2026?
On 2026-09-14, the highest mobile speed score among the 24 Shopify themes we have tested is Dawn by Shopify at 92 out of 100, measured with Google Lighthouse on its demo store. Rankings change as themes are re-tested, so the live table above is the current answer.
How are Shopify themes tested?
Each theme's own demo store is run through Google's PageSpeed Insights API (Lighthouse) on mobile and desktop, for the home page and, where the platform has them, a collection page and a product page. A theme's headline score is the median of its presets; a preset's is the mean of its pages. Every run is kept, so scores have a history and are re-measured continuously.
What is a good Lighthouse score for a Shopify theme?
Google's bands are 90–100 good, 50–89 needs improvement, 0–49 poor. The median mobile speed score across tested Shopify themes is 78, and 2 of 24 (8%) reach 90 or better. Mobile scores run well below desktop for the same theme because Lighthouse simulates a mid-range phone on a slow connection.
