Pinterest is more than just a mood board—it’s a powerhouse for driving e-commerce sales. With over 450 million active users worldwide, Pinterest offers a unique platform for brands to reach highly engaged audiences. But here’s the catch, your visual strategy can make or break your ad performance. Specifically, your image size and dimensions play a crucial role in determining your ad engagement rates.
This blog dives into the science and stats behind how Pinterest ad performance correlates with image specifications. You’ll discover optimal image dimensions, industry benchmarks, and the specific strategies that help drive ROI for e-commerce brands.
Why Image Dimensions Matter on Pinterest
Before jumping into optimal image sizes, it’s important to understand why dimensions play such a significant role on Pinterest. Unlike other platforms, Pinterest serves as a visual discovery tool. The effectiveness of your content often hinges on how quickly and effectively it grabs attention—often within seconds.
Pinterest favors visuals that are optimized to their specific platform dimensions. Images that are too large, too small, or incorrectly formatted may appear distorted, blurry, or cropped, negatively impacting viewer engagement.
Key reasons why size matters:
- Pinterest’s grid-style interface favors taller images because they visually dominate screen space.
- High-quality visuals ensure clarity, enhancing click-through rates (CTR) and saves.
- Proper formatting ensures your ad meets Pinterest’s guidelines without being cropped or rejected.
Now that we know why size matters, let’s discuss the ideal image specifications.
The Best Image Dimensions for Pinterest Ads
Pinterest provides clear guidelines around image sizing to help advertisers create engaging pins. Here are the key recommendations and the rationale behind them:
Standard Pins
Aspect Ratio: 2:3
Recommended Size: 1000 x 1500 pixels
Why it works:
- Pinterest recommends this aspect ratio because it looks visually balanced on both desktop and mobile displays without getting cropped.
- Research shows pins with the 2:3 aspect ratio generate 70% higher impressions and engagement compared to non-optimized pins.
Long Pins for Storytelling
Aspect Ratio: 1.3 – 2.3 (e.g., 1000 x 2100 pixels)
Use Case:
- Long pins work best for DIY guides, infographics, or step-by-step visuals. These taller formats help businesses tell a story effectively.
- Be cautious! Images longer than 2.3 may be truncated, reducing impact.
Carousel Ads
Image Size: Minimum 1000 x 1500 pixels
Aspect Ratio: Same as standard pins (2:3)
Use Case:
- Perfect for showing multiple products or conveying step-by-step processes. The swipeable feature can showcase up to 5 images, each adhering to Pinterest’s size guidelines.
Video Pins
- Specs for Vertical Video Ads:
- Aspect Ratio: 9:16
- Ideal Dimensions: 1080 x 1920 pixels
Video ad engagement rates on Pinterest have shown an 8% higher CTR compared to static pins, but it’s crucial to maintain the right aspect ratio to maximize visibility.
Image Quality and Technical Requirements
Pixel-perfect images aren’t just about dimensions—they must also meet certain technical quality benchmarks. Here are three key areas your team should focus on to ensure engaging and professional ads on Pinterest.
File Size and Format
- File Size: Maximum 20MB for static images and 2GB for video ads.
- File Formats: Pinterest supports JPEG and PNG for images. For video, use MP4.
Stick to these file formats to ensure no loss in clarity or detail—and improve ad approval rates.
Clarity and Focus
Pinterest’s audience skews heavily towards mobile users. Blurry, low-resolution images are immediately disregarded, leading to poor ad performance. Always aim for 300 DPI resolution for your ad creatives.
Contrast and Branding
High-contrast colors help pins stand out in crowded feeds. Adding your branding or logo subtly within the image ensures better product recall without overwhelming the viewer.
Engagement Metrics by Image Type
Understanding how different image types contribute to ad performance is a game-changer. Here’s what data shows about engagement rates based on image specifications and types.
Standard Product Images
- Average CTR: 1.4%
- Best Use: Ideal for product-focused pins in e-commerce campaigns.
- Pro Tip: Pair a compelling call-to-action within your pin descriptions to boost engagement.
Infographics (Long Pins)
- Average CTR: 2%
- Save Rate (Repins): Higher than any other image type due to their shareable and informative nature.
- Best Use: Perfect for fitness, recipes, or travel-related topics.
Lifestyle Images
- Average CTR: 1.7%
- Best Use: Showing products in real-life settings (e.g., product flatlays, home décor setups) inspires users and enhances clickable appeal.
Carousel Ads
- Engagement Time (per swipe): 4 – 5 seconds
- Best Use: Use these ads to showcase collections or highlight additional features of individual products.
By analyzing these benchmarks, you can target and optimize engagement strategies.
Case Study: Real Campaign Data
Take, for example, a campaign for an e-commerce fashion brand selling sustainable handbags. Over 3 months, the brand ran two sets of pins:
- Images optimized to Pinterest-recommended specs (2:3 aspect ratio, 1000 x 1500 pixels).
- Images with unconventional dimensions (e.g., square or overly wide).
Results:
Optimized images achieved:
- 57% higher Click-Through Rates (CTR)
- 34% lower CPM (Cost Per Thousand Impressions)
- 2.5x return-on-investment (ROI)
Pins that adhered closely to Pinterest guidelines generated much higher engagement. This demonstrates how visual optimization impacts direct results on paid ad campaigns.
Visual Optimization Strategies for E-Commerce
For e-commerce brands, success on Pinterest heavily relies on visual appeal. Here’s how to get ahead of the game while maintaining alignment with optimal image sizing recommendations.
- A/B Test Ad Creatives
Experiment with varying pin layouts, colors, and styles within the same aspect ratio to identify what resonates most with your audience.
- Focus on Repin Potential
Create “evergreen” content like inspirational quotes, DIY projects, or usable templates. These maximize engagement long after the initial pinning.
- Leverage Bold Typography
For text-over-image pins, use bold fonts to communicate your message clearly. Overlayed text works best on lifestyle photos or product close-ups.
- Invest in High-Quality Photography
Professional photography boosts perceived brand value and encourages clicks. Poor lighting and amateur setups can turn users away.
