The Complete Shopify Image Size Guide (2025)

Shopify Banner Size & Image Guide: The Only Resource You Need in 2025

You've just uploaded a stunning new hero banner to your Shopify store. It looks perfect on your laptop. But when you check it on your phone? Disaster. The text is cut off, the model's head is missing, and the whole thing looks blurry.

If this sounds familiar, you aren't alone. Managing Shopify banner sizes and image dimensions is one of the most frustrating parts of running an online store. With different themes, devices, and screen resolutions, there is rarely a "one size fits all" solution.

But here is the good news: getting your images right is the single highest-ROI design change you can make. Crisp, fast-loading images build trust instantly. Blurry or cropped ones scream "amateur."

In this comprehensive guide, we will break down the exact dimensions for every image on your Shopify store—from hero banners to product thumbnails—and show you how to ensure they look perfect on every device.

The Quick Cheat Sheet: Best Shopify Image Sizes for 2025

In a hurry? Here are the recommended dimensions you should stick to for most Shopify 2.0 themes (like Dawn, Sense, and Impulse).

• Shopify Banner Size (Desktop): 1920 x 1080 px or 1600 x 600 px (depending on section height)
• Shopify Banner Size (Mobile): 800 x 1200 px (portrait) or 800 x 800 px (square)
• Product Images: 2048 x 2048 px (Square 1:1 ratio)
• Collection Images: 1024 x 1024 px (Square 1:1 ratio)
• Blog Post Featured Image: 1200 x 630 px (1.91:1 ratio) or 1200 x 800 px
• Logo size: 200 x 200 px (upload size), typically displayed at 100-250px width

Shopify Banner Size: The Hero Section Dilemma

Your hero banner is your store's digital storefront. It is the first thing customers see, but the "correct" Shopify banner size depends heavily on how your theme handles responsiveness.

Recommended Desktop Dimensions

For most desktop screens, a 1920 x 1080 px image is the gold standard. This 16:9 aspect ratio fills the screen nicely without being too tall. However, if you want a slimmer banner (so users can see products below the fold immediately), opt for 1920 x 600 px.

Pro Tip: Keep your essential content (text, main subject) in the center. Many themes will crop the left and right edges on smaller laptops or tablets.

The Mobile Crop Issue

This is where 90% of merchants fail. If you use a wide desktop banner (16:9) on a mobile phone (9:16), your theme will do one of two things:

1. Shrink it: The image becomes tiny, and text becomes unreadable.
2. Crop it: The theme zooms in on the center, cutting off your beautiful design.

The Solution: Use a theme or section that allows for separate desktop and mobile images. If your current theme doesn't support this, you are fighting a losing battle.

For mobile-specific banners, we recommend 800 x 1200 px. This takes up more vertical screen real estate, which is perfect for grabbing attention on Instagram or TikTok traffic.

Struggling with a theme that chops off your banners? At Section Store. They come with built-in mobile optimization settings, letting you upload separate images for desktop and mobile without writing a single line of code.

Product Image Sizes: Quality Meets Speed

While banners sell the brand, product images sell the item. Shopify allows images up to 4472 x 4472 px, but that is overkill and will slow down your site.

The Golden Rule: 2048 x 2048 Pixels

Square images (1:1 aspect ratio) are the industry standard for ecommerce. They stack perfectly on mobile grids and look consistent on collection pages. We recommend 2048 x 2048 px because:

• It allows for high-quality "Zoom" functionality (requires at least 800x800px).
• It is crisp enough for Retina displays.
• Shopify's servers will automatically create smaller versions for thumbnails, so you don't need to worry about file size bloat as long as the original is compressed (more on that later).

Consistency is King

Nothing kills trust faster than a collection page where one image is portrait, the next is landscape, and the third is square. It makes your layout look broken. Even if your original photos vary, use a photo editor to crop them all to a 1:1 square ratio before uploading.

Collection Image Sizes

Collection images often appear as thumbnails on your homepage or as headers on collection pages. Stick to 1024 x 1024 px.

If your theme uses a "banner" style for collection headers, you might need a rectangular version (like 1200 x 400 px). Always check your specific theme's documentation, as this varies more than product images.

Blog Post and Article Images

Content marketing is a great way to drive traffic (you are reading this, aren't you?). For your blog:

• Featured Image: 1200 x 630 px. This is the standard size for Facebook and Twitter (X) sharing cards. If you use this size, your links will look perfect on social media automatically.
• In-Content Images: Width of 1000 px is usually sufficient. Ensure the file size is small (under 200kb) to keep the page load speed fast.

File Formats: JPG vs. PNG vs. WebP

Choosing the right file type is just as important as the dimensions.

JPG (JPEG)

Best for: Photos, product images, banners with many colors. Why: It handles complex colors efficiently and keeps file sizes low. 90% of your store's images should be JPGs.

PNG

Best for: Logos, icons, and images with transparent backgrounds. Why: It offers lossless quality but creates massive file sizes for photographs. Never use PNG for a hero banner unless it's a vector-style graphic with few colors.

WebP

Best for: Everything (modern web standard). Why: WebP offers the quality of PNG with file sizes smaller than JPG. Shopify now automatically serves WebP images to browsers that support them, so you can usually just upload JPG/PNG and let Shopify do the magic.

Optimization: Don't Kill Your Page Speed

You can have the perfect shopify banner size, but if the file is 5MB, your customer will bounce before it loads.

Target File Sizes

• Hero Banners: Under 500 KB
• Product Images: Under 300 KB
• Blog Images: Under 200 KB

How to compress? Use free tools like TinyPNG or Shopify apps. Never upload raw images directly from a DSLR camera (which can be 10MB+).

Common Mobile Responsiveness Pitfalls

Mobile traffic now accounts for over 70% of ecommerce visits. Yet, most merchants design on desktop and treat mobile as an afterthought.

Section Store sections always include both desktop and mobile images so you can customise perfectly for all devices.

The "Center Focus" Problem

On mobile, a landscape image is often cropped to the center. If your text is on the far left or right of your banner image, it will vanish on mobile. Always use the "Safe Zone" principle: keep critical elements in the center 50% of the image.

Text Overlay: Image vs. HTML

Don't embed your text inside the image file (e.g., using Photoshop to write "Sale 50% Off" on the photo). This text:

1. Won't scale properly on mobile (it will become tiny).
2. Can't be read by Google (bad for SEO).
3. Can't be edited easily later.

Instead, use your theme or section settings to overlay HTML text on top of the background image. This ensures the text remains readable and resizable on any device.

Need a text-overlay section that actually looks good? Our Hero Sections are designed to keep text legible on screens as small as an iPhone SE. Plus all the coding is done for you so the image + text scales perfectly for all device sizes.

How to Find Your Theme's Specific Requirements

While this guide covers 95% of use cases, some custom themes have quirky requirements. Here is how to check yours:

1. Theme Documentation: Go to the theme developer's website and search "image sizes."
2. Inspect Element: Right-click an image on your store demo, choose "Inspect," and hover over the image code to see the "Rendered size." This tells you exactly what pixel dimensions the browser is displaying.
3. Trial and Error: Upload a test image with a grid overlay to see exactly where your theme cuts it off.
