Your Shopify store has to be fast. That’s a fact – if your website takes ages to load, potential customers will leave before getting a chance to buy. Plus, a fast website is bound to get better Google rankings, as the search engine prioritizes websites with quicker loading times.

There is a number of things you can do to speed up your Shopify store. The first one - choosing the right theme. And while all Shopify pages are using the same Shopify servers, one thing is different and it affects speed massively – and that is your Shopify theme.

In this post, we’ll be talking about the fastest Shopify themes. Lightweight, and beautifully optimized, they’ll store load fast, rank high, and sell big.

How does a Shopify theme make your store faster?

What separates a fast Shopify theme from a slow one? Well – here are some of the things Shopify themes do to make sure your store loads as quickly as possible.

  1. Less code. The math is simple – the less code there is to load, the faster it will load. The fastest Shopify theme options try to minimize the amount of code used to display your site.
  2. Cleaner CSS and inline CSS. This means that the visitor’s browser will only need to download one file instead of two – making the loading speeds quicker.
  3. No relying on external libraries. Many themes still rely on the outdated jQuery JavaScript library, known for causing slower loading times. By not relying on external libraries at all, fast Shopify themes can minimize the load times.

Naturally, for our list, we included the themes that use all the industry's best website speed practices.

Automatic image optimization makes sure that the visuals don’t lose their quality, but drop down massively in file size. Modular Javascript loads only the essentials, without the bloat, and it’s often not used at all, thanks to additional CSS implementations. This can help you speed up your website by quite a lot.

With exciting sales features, such as geo-personalized content, multitab shopping sync, and a lookbook feature so your visitors can browse products right from a set picture, Booster adds a lot of premium stuff entirely free of charge. It costs $249 a year – or $399 for unlimited lifetime access. It’s a great theme for medium-sized shops looking to offer a premium shopping experience – with excellent speeds to match.

Additional third-party apps for banners, pop-ups, badges, and much more can also negatively affect your site’s load times.

All of the designs and code in the features are fully optimized to work with this theme specifically. This means you’ll be able to use all of the fun stuff, without the speed penalty.

What should you consider when choosing a fast Shopify theme?

There is no one correct answer which is the fastest Shopify theme. When looking to build a super-fast store with one of these themes, consider a few very important things.

  • More features = less speed. If a website is a blank page with nothing interesting, it will be very fast. But is that what you want? Sometimes, speed is a penalty websites pay for better website design.
  • Minimize the unused code. This is where the real performance gains are. Best Shopify themes focus on removing the unnecessary – that’s what the themes on our list are set out to do.
  • Real-life experience matters. You’re making a store for people, not machines. Performance scores don’t mean much if the website isn’t blazing fast and buttery smooth to use.
  • Media is the speed killer. A massive high-quality image or a video file will plunge all your speed metrics to the ground. Not even the fastest theme can save you if your media is massive.

Other ways to make your store faster

A theme alone is not going to make your store faster. There are plenty of other ways you can improve your Shopify store speed.

Hosting media externally can be a lot of help. Videos uploaded to a sharing service, and not your site can reduce loading time by a lot. You can also remove a lot of strain to your site by using apps more effectively, lazy loading images below the fold, and compressing your existing media to a smaller file size.

Finally, regular website analysis can help you see the issues with broken links, redirects, and other factors that slow down your store. Always make sure to look after your page – and that goes beyond just getting a flashy new theme.

Final words

Fast loading Shopify themes can help you positively impact your site’s performance, leading to higher Google search rankings and better conversions. Therefore, it’s important to choose a theme that’s lightweight and offers a lot of features that would reduce the need for several third-party apps.

However, your site’s performance will depend on a lot of other factors – themes like Shoptimized or Shella are amazing starting points, but for best results, you will still need to work.
