1.91 x 1 Aspect Ratio Guide for Social Media Ads

Mastering the 1.91 x 1 Aspect Ratio for Social Media Ads

The 1.91 x 1 aspect ratio is a marketing standard that can dramatically boost the appearance and performance of your Facebook and Instagram feed ads. This horizontal format is nearly twice as wide as it is tall, making it ideal for showcasing products, events, or scenery in a way that feels native to user feeds and maximizes visibility. In this guide, you’ll learn why this ratio is recommended, the exact pixel sizes to use, how to design for it in popular tools, and the best practices to keep your creatives compelling and click‑worthy.

Understanding the 1.91 x 1 Aspect Ratio

The 1.91 x 1 aspect ratio defines the relationship between width and height in an image.

Formula:

• Width ÷ Height = 1.91

For example, if your height is 628 px, your width should be about 1,200 px. This proportion offers a sleek, clean rectangle that fits perfectly in social media feeds without awkward cropping or wasted space.

Why Facebook & Instagram Recommend 1.91 x 1

Both Facebook and Instagram optimize their feeds for smooth visual flow:

• Maximizes on‑screen presence without overwhelming the layout.
• Keeps ads consistent with organic content, reducing user resistance.
• Prevents auto‑cropping that can cut off critical design elements.
• Fits comfortably on mobile screens, leaving room for captions and call‑to‑action buttons.

Standardizing on this ratio ensures your ad creative is sharp, well‑balanced, and aligned with platform best practices — which can help lift click‑through rates.

Designing 1.91 x 1 Images in Canva

Canva provides an easy entry point for non‑designers:

1. Open Canva → Custom Size.

3. Insert background images aligned to the frame.
4. Add text and graphics with adequate padding.
5. Export as PNG or JPEG for upload.

Designing in Photoshop

For more advanced control:

File → New → Width: 1200 px, Height: 628 px, Resolution: 72 dpi

• Set Guides to define safe zones.
• Design in distinct layers for flexibility.
• Use Save for Web to balance quality and file size.

Cropping and Resizing Without Distortion

If you’re adapting existing images:

• Maintain proportions via “constrain proportions” settings.
• Crop strategically to retain key subjects in frame.
• Add padding or background filler to avoid cutting vital elements if dimensions don’t fit naturally.

Mobile vs Desktop Display Considerations

Although the ratio remains the same, the on‑screen experience changes:

Preview on multiple devices to confirm your creative’s effectiveness everywhere.

Best Practices for Text Placement

Effective text layout inside a 1.91 x 1 frame:

• Keep crucial text within the central 80% of both width and height.
• Use high‑contrast fonts for legibility against image backgrounds.
• Position call‑to‑action buttons away from the edges to prevent accidental cropping.

---

Testing and A/B Comparison

Optimize your creatives through structured testing:

1. Design two variations with identical dimensions.
2. Run both under the same campaign conditions.
3. Monitor click‑through rate, engagement, and conversions.
4. Double down on the better‑performing design.

This isolates the content’s impact while keeping the technical format constant.

Common Mistakes to Avoid

Even with the right dimensions, errors can hurt performance:

• Low resolution images stretched to fit the frame.
• Text cut‑off by ignoring safe zones.
• Poor mobile adaptation leading to obstructed visuals.

Prevent these with pre‑flight design checks and platform previews.
