Amazon A+ Content Image Size: Verification Checklist

This article provides a verification checklist for AmazonA+ Contentimage sizes in 2026. You'll learn the exact dimension requirements, common pitfalls, and practical steps to ensure your images meet Amazon's standards, helping you avoid listing rejections and improve customer engagement.

Why Amazon A+ Content Image Size Matters in 2026

For cross-border sellers, Amazon A+ Content is a key tool to differentiate products and increase conversion rates. However, incorrect image sizes or formats can lead to listing suppression or poor mobile rendering. As of 2026, Amazon has updated its guidelines to emphasize mobile-first design, making compliance with image size requirements more critical than ever.

This checklist helps you verify every image in your A+ modules before upload. By following it, you can avoid time-consuming rejections and ensure your content displays correctly across all devices, enhancing customer trust and sales.

Key Amazon A+ Content Image Size Requirements: Categories and Types

Amazon A+ Content includes several module types, each with specific image size and aspect ratio guidelines. The main categories are: standard image modules (full-width banners, single image, multiple images), comparison charts, and text-plus-image modules. For each, Amazon specifies minimum dimensions, recommended DPI, and file formats.

Typical requirements (indicative as of 2026, subject to official updates):

Full-width banner: 3000 x 600 pixels (or 3000 x 1200 for some modules), JPEG or PNG, max 10 MB. Single image module: 3000 x 3000 pixels (square), JPEG/PNG/TIFF. Comparison chart images: 300 x 300 pixels minimum, but recommended 1000 x 1000 for clarity. Text-plus-image modules: images should be at least 3000 x 3000 pixels for zoom, but the displayed size may be smaller.

Always check the latest guidelines in Seller Central, as Amazon occasionally revises these numbers. For cross-border sellers, it's also important to consider file compression to maintain loading speed without sacrificing quality.

• Full-width banner: 3000×600 px, JPEG/PNG, max 10 MB
• Single image: 3000×3000 px, square, JPEG/PNG/TIFF
• Comparison chart: min 300×300 px, recommended 1000×1000 px
• Text-plus-image: 3000×3000 px for zoom, but displayed smaller
• File formats: JPEG, PNG, TIFF (no GIF or BMP)

How to Evaluate Image Size Requirements: Criteria and Trade-offs

When preparing A+ images, you must balance resolution, file size, and loading speed. High-resolution images (e.g., 3000px) are essential for zoom functionality, but they can increase file size, leading to slower page loads—especially on mobile. Amazon recommends a maximum file size of 10 MB per image, but for optimal performance, aim for 1-2 MB.

To evaluate your images, use the following criteria:

1. Dimension accuracy: Verify that each image meets the minimum pixel dimensions for its module. Use image editing software to check exact pixel dimensions.

2. Aspect ratio: Ensure the aspect ratio matches the module template (e.g., 5:1 for banners, 1:1 for single images). Cropping incorrectly can distort the image.

3. File format: Use JPEG for photographs, PNG for graphics with transparency. TIFF is accepted but rarely needed.

4. Compression: Compress images without visible quality loss. Tools like TinyPNG can reduce file size by up to 70%.

5. Mobile view: Test how images appear on a mobile device. Amazon now prioritizes mobile layouts, so ensure text is legible and images are not cropped on small screens.

Trade-offs: Higher resolution improves zoom quality but increases load time. If your product doesn't require zoom, you can use smaller images to speed up the page. However, for main product images, always adhere to the 3000px requirement to enable zoom.

Common Pitfalls When Dealing with A+ Image Sizes

Many sellers face issues with A+ content approval due to avoidable mistakes. Here are the most common pitfalls:

1. Using images with insufficient resolution: Uploading a 1000px image where 3000px is required will trigger a rejection. Always upscale images to the exact minimum, but avoid upscaling low-quality images as they will appear blurry.

2. Incorrect aspect ratio: Forcing a square image into a banner module without proper cropping results in distortion or unwanted white space.

3. File size too large: Images over 10 MB are rejected. Even if under 10 MB, large files slow down page load, hurting user experience and SEO.

4. Ignoring mobile responsiveness: Text within images may be too small to read on phones, or images may be cropped. Amazon's mobile app displays A+ content differently, so always preview on mobile.

5. Using prohibited file types: GIF and BMP are not supported. Stick to JPEG, PNG, or TIFF.

To avoid these pitfalls, create a pre-upload checklist: verify dimensions, aspect ratio, file size, and mobile preview for every image. Use Amazon's built-in preview tool in Seller Central before submitting.

Practical Recommendations and Next Steps

To ensure your A+ content meets all image size requirements, follow these actionable steps:

1. Download the latest Amazon A+ Content Style Guide from Seller Central—it contains the most current specifications.

2. Use a spreadsheet to track each module's image requirements, and fill in the actual dimensions of your images before upload.

3. Invest in a reliable image editing tool (e.g., Adobe Photoshop, Canva Pro) to resize and compress images accurately.

4. Test your images on multiple devices (desktop, iOS, Android) using Amazon's mobile preview feature.

5. Keep a template library of approved image sizes for different modules to speed up future content creation.

By implementing this checklist, you can reduce rejection rates and improve the visual appeal of your product pages, leading to higher conversion rates.
