1.91:1 Aspect Ratio in Pixels for Social Media Graphics

Introduction to the 1.91:1 Aspect Ratio for Social Media

When designing images for ads or posts, getting the proportions right is essential for visual appeal and platform compatibility. The 1.91:1 aspect ratio is a widely used format for social media, striking the ideal balance between width and height for optimal feed presentation. This guide explains what the 1.91:1 ratio means in pixels, why it’s preferred across major platforms, and how to create perfectly proportioned images without distortion or cropping.

Understanding the 1.91:1 Aspect Ratio

The 1.91:1 aspect ratio is a specific proportional relationship between the width and height of an image. In simpler terms:

• Width → 1.91 units
• Height → 1 unit

This means for every pixel of height, the image is 1.91 pixels wide. It's wider than the "traditional" 16:9 video ratio and is highly optimized for certain social media placements.

Mathematically:

Width / Height = 1.91

For instance, if your image is 1910 pixels wide, the height should be 1000 pixels to match exactly.

Why Social Media Loves 1.91:1

The 1.91:1 ratio is widely adopted by platforms because it strikes a balance between visibility, readability, and aesthetic layout:

Common Use Cases

• Facebook Ads (Single Image)
• Facebook recommends 1200 × 628 px (which is exactly 1.91:1) for link advertisements.
• LinkedIn Sponsored Content
• LinkedIn also uses this ratio for optimal display in their feed.
• Twitter Cards
• Summary large image cards often render beautifully with 1.91:1.

These formats ensure content isn't cropped awkwardly and fully utilizes screen width without appearing too tall.

Converting 1.91:1 to Pixels

To use this aspect ratio effectively, you often start with a pixel width and then calculate the pixel height to match.

Formula:

Height = Width / 1.91

Example Calculations:

1. Width: 820 px
2. Width: 1080 px

   Height = 1080 / 1.91 ≈ 566 px

   Height = 820 / 1.91 ≈ 429 px

1. Width: 1200 px

   Height = 1200 / 1.91 ≈ 628 px

Step-by-Step Calculation Guide

1. Choose your preferred width based on platform requirements or your design.
2. Apply the formula:

• Divide width by 1.91

1. Round to the nearest whole pixel to avoid fractional values in exports.

Example:

Given width = 1500 px
Height = 1500 / 1.91 ≈ 786 px

Best Image Sizes for Social Media

Recommendations

• Facebook Link Ads: 1200 × 628 px
• LinkedIn Ad Creative: 1200 × 628 px
• Twitter Image Card: 1200 × ~628 px (exact calculation with integer rounding)
• Pinterest Ads (custom wide): 1000 × ~523 px for variety, if permitted.

These dimensions ensure minimal cropping across devices and platforms.

Maintaining Clarity and Sharpness

Image clarity depends on resolution, compression, and export settings.

Tips:

• Use PNG for graphics/text – avoids compression artifacts.
• JPEG at high quality (80–90%) for photos – balances file size and clarity.
• Check platform compression rules – some platforms automatically reduce resolution.
• Design at 2x resolution for retina screens — e.g., for a required 1200 × 628 px, work at 2400 × 1256 px and scale down.

Tools & Calculators for Quick Values

Several online tools help you determine exact pixel dimensions for a given aspect ratio:

• Aspect Ratio Calculator – input width & ratio, get height instantly.
• Canva / Figma – supports custom canvas sizing in pixels.
• Photoshop / GIMP – offers constraint locking for ratios during resizing.

These save time when preparing assets for various platforms.

Avoiding Distortion and Cropping Issues

When exporting:

1. Lock aspect ratio in your design canvas to avoid unintentional stretch.
2. Check safe zones – crucial for ads where text or logos must remain visible after cropping.
3. Preview in platform UI before publishing – catches unexpected offsets.

Distortion occurs when you change one dimension without adjusting the other according to the ratio. Cropping issues arise when uploading images slightly taller or wider than platform guidelines—platforms will crop automatically, sometimes cutting vital content.
