I Tested 17 Popular Shopify Themes: Real Load Times & Speed Scores (2026)

A few months ago, a client asked me a deceptively simple question: Which Shopify theme is actually the fastest?

I went to Google expecting to find a definitive, data-backed answer comparing homepage and product page speeds. Instead, I found marketing fluff and outdated listicles. Nobody was publishing concrete, out-of-the-box performance metrics.

So, I built a controlled environment and tested 17 popular Shopify themes myself.

I ran over 204 individual Lighthouse audits across 17 of the most used free and premium Shopify themes. I am making this data public so store owners and developers can choose their next theme based on real metrics—all raw audit reports are linked in the public repository.

TL;DR: If you just want the final numbers, scroll straight down to the tables at the bottom of this post.

Testing Methodology

To ensure the data is unbiased and accurate, I tested every theme under the exact same conditions.

• The Environment: A fresh Shopify Development store populated with Shopify's default test data (13 demo products). Zero third-party apps were installed to prevent script interference.
• The Pages Tested: The Homepage and a standard Product Page for every theme.
• The Audits: I ran 3 consecutive Lighthouse tests per page, per viewport (Mobile and Desktop). To eliminate network anomalies or random CPU spikes, I discarded the highest and lowest scores and recorded the median result.
• The Tool: Because Shopify development stores are password-protected, standard browser-based PageSpeed Insights URLs will not work. I used the Lighthouse CLI via a custom Node.js script to bypass the password wall and audit the raw storefront.

Disclaimer: Your mileage will vary. These scores represent the absolute baseline performance of a theme. Once you add high-resolution banners, tracking pixels, and third-party apps, these numbers will change—but this data reveals which themes give you the best foundational head start.

Themes Tested

I picked a combination of themes which are widely used in Shopify. Some of these are paid and others are free.

#	Theme	Free/Paid
1	Broadcast	Paid
2	Dawn	Free
3	Craft	Free
4	Spotlight	Free
5	Studio	Free
6	Origin	Free
7	Sense	Free
8	Refresh	Free
9	Expanse	Paid
10	Horizon	Free
11	Impact	Paid
12	Be Yours	Paid
13	Impulse	Paid
14	Prestige	Paid
15	Symmetry	Paid
16	Palo Alto	Paid
17	Motion	Paid

Overall Rankings (Mobile vs Desktop)

While premium themes often boast about their heavy feature sets, the data proves that you don't necessarily have to sacrifice speed for functionality.

The baseline scores reveal a tight race, with several free Shopify 2.0 framework themes matching the performance of high-end paid options.

Expanse 1.23s

Broadcast 1.34s

Symmetry 1.50s

Sense 1.73s

Craft 1.73s

Here is how they stack up when combining both mobile and desktop scores.

Rank	Theme	Mobile Score	Desktop Score	Mobile LCP	Desktop LCP
🥇	Expanse	100	100	1.23s	0.57s
🥈	Origin	100	100	1.74s	0.52s
🥉	Broadcast	99	100	1.34s	0.33s
4	Symmetry	99	96	1.50s	0.59s
5	Sense	99	100	1.73s	0.53s
6	Craft	99	100	1.73s	0.52s

11	Horizon	99	100	1.92s	0.58s
12	Refresh	98	100	1.89s	0.57s
13	Impulse	97	98	2.32s	0.97s
14	Prestige	94	97	1.78s	0.71s
15	Motion	94	85	2.62s	1.25s
16	Be Yours	89	98	3.08s	0.60s
17	Palo Alto	72	94	2.16s	0.97s

Mobile Performance (Detailed)

The mobile speed test for these is where themes actually break. Overall scores are great for a quick glance, but mobile performance is the only metric that truly dictates your bounce rate.

Google uses mobile-first indexing, and over 70% of Shopify traffic comes from smartphones. This is where heavy JavaScript payloads expose poorly optimized themes. When reviewing the mobile data below, pay close attention to Total Blocking Time (TBT).

A high TBT means the store might look loaded, but the customer’s phone is completely frozen while background scripts finish executing.

Rank	Theme	Score	LCP (s)	CLS	TBT (ms)	Page Size (MB)	Requests	Fully Loaded (s)
1	Expanse	100	1.23	0.001	89	0.20	222	2.26

17	Palo Alto	72	2.16	0.000	972	0.15	117	3.91

Desktop Performance (Detailed)

While Desktop performance doesn't impact many stores since B2C ecommerce traffic is overwhelmingly mobile but it matters a lot in B2B, where the high-ticket advantage stays for store owners.

Desktop shoppers might make up a smaller percentage of total traffic, but they typically carry a much higher Average Order Value (AOV). Desktop is also where complex mega-menus, heavy filtering, and high-resolution lifestyle imagery come out to play.

Fortunately, modern web browsers handle desktop rendering beautifully, but this data highlights which themes maintain absolute perfect visual stability (0.00 CLS) while loading heavy assets.

Rank	Theme	Score	LCP (s)	CLS	TBT (ms)	Page Size (MB)	Requests	Fully Loaded (s)
1	Broadcast	100	0.33	0.000	0	0.10	108	0.33
2	Dawn	100	0.52	0.000	0	0.43	160	0.52
3	Craft	100	0.52	0.000	0	0.07	150	0.52

Key Takeaways

The biggest takeaway from testing 204+ page loads is that Shopify’s default free themes (like Dawn and Craft) are incredibly well-optimized right out of the box. However, if you have the budget, premium themes like Expanse and Broadcast prove that you can have advanced merchandising features, complex layouts, and sub-second load times without compromising on performance. Your theme is just your foundation—protect these scores by being ruthless about which third-party apps you install next.

How to Choose a Fast Shopify Theme

Based on this test, here’s my advice:

1. Start with a lightweight theme (see the top 3 in the table).
2. Always run PageSpeed Insights on the theme’s demo store before buying.
3. Avoid themes with built‑in heavy features you don’t need (sliders, animations, page builders).
4. If you already own a slow theme, don’t panic, custom development can often fix speed issues without switching.
5. Remember: speed is important, but design and functionality still matter. Choose a theme that balances both.
