Choosing the Right Video Size for Shopify Websites
Share
When adding a video banner to a Shopify store, selecting the correct dimensions is important for both visual impact and performance. Since most Shopify themes are responsive, your banner needs to look strong on desktop while still working smoothly on mobile.
Desktop Banner Video Size for Shopify
For desktop, 1920 × 1080 (16:9) is the standard format. This widescreen ratio is commonly used for YouTube and fits perfectly into full width hero sections in most Shopify 2.0 themes.
A 16:9 video works especially well for:
-
Full width homepage hero sections
-
Announcement or promotional banners
-
Cinematic brand storytelling
Because desktop screens are horizontal, this format displays naturally without excessive cropping.
Using the Same Video on Mobile
In some cases, the 1920 × 1080 version can also be used on mobile. However, this depends on how the video is composed.
If the main subject stays centered with safe spacing on the left and right sides, the theme can crop it responsively without losing important elements. If key visuals or text sit near the edges, they may be cut off on smaller screens.
When that happens, a separate mobile version is recommended.
Recommended Mobile Video Sizes for Shopify
For mobile hero sections, these formats are commonly used:
1080 × 1920 (9:16)
Ideal for full screen vertical hero banners. This creates an immersive experience and feels native to modern smartphones.
1080 × 1350 (4:5)
A slightly shorter vertical format that maintains strong visual presence without taking up excessive scroll space.
Performance Matters on Shopify
Video banners can impact load speed, especially on mobile. To maintain good performance and Core Web Vitals:
-
Compress videos properly
-
Keep mobile files smaller than desktop versions
-
Consider adding a fallback image
Since Shopify stores rely heavily on conversion rates, balancing visual impact with fast loading speeds is critical.
Final Recommendation
If possible, plan for both desktop and mobile from the beginning. Designing with safe zones allows you to crop efficiently. When high visual precision is required, creating a dedicated vertical video for mobile usually delivers the best result.
Optimizing your banner video correctly ensures your Shopify store looks professional, loads efficiently, and performs well across all devices.
