Aspect Ratio Guide

What is Aspect Ratio?

The proportional relationship between width and height.

Common Aspect Ratios:

Maintaining Aspect Ratio

When to Maintain:

• ✅ Photos (prevent distortion)
• ✅ Graphics with people/objects
• ✅ Professional work
• ✅ Most general use cases

When to Change:

• ✅ Specific platform requirements
• ✅ Creative cropping
• ✅ Background images
• ✅ When you control the composition

How It Works:

• Enable "Maintain aspect ratio"
• Change width OR height
• Other dimension adjusts automatically
• Prevents stretching/squashing

Resize Methods Explained

Fit (Contain)

What it does:

• Scales image to fit within dimensions
• Maintains aspect ratio
• May leave empty space (letterboxing)

Best for:

• Photos where you need entire image visible
• Product photos
• Portraits

Fill (Cover)

What it does:

• Scales image to fill dimensions
• Maintains aspect ratio
• Crops edges if needed

Best for:

• Background images
• Thumbnails
• When exact dimensions required

Stretch

What it does:

• Forces exact dimensions
• Ignores aspect ratio
• Distorts image

Best for:

• Textures and patterns
• When distortion is acceptable
• Avoid for photos

Crop

What it does:

• Manual selection of area
• Cuts to exact dimensions
• You control composition

Best for:

• Reframing photos
• Removing unwanted elements
• Creating specific compositions

Quality Considerations

Resizing Down (Making Smaller):

• ✅ Generally safe
• ✅ Reduces file size
• ✅ Maintains quality
• ✅ Recommended for web

Tips:

• Keep original as backup
• Resize to exact display size
• Compress after resizing

Resizing Up (Making Larger):

• ❌ Quality loss inevitable
• ❌ Image becomes pixelated
• ❌ Details become blurry
• ❌ Avoid if possible

If You Must:

• Use AI upscaling tools (external)
• Limit to 10-20% increase
• Expect some quality loss
• Consider re-shooting/re-acquiring

File Size Impact

General Rule:

• Halving dimensions = ~1/4 file size
• Doubling dimensions = ~4x file size

Examples:

Note: Actual size depends on format and compression

Batch Resizing

Using Workflow Builder:

1. Upload multiple images
2. Add "Resize" operation
3. Set target dimensions
4. Choose resize method
5. Process all images
6. Download resized batch

Use Cases:

• Product photo standardization
• Social media batch preparation
• Thumbnail generation
• Email attachment preparation

Troubleshooting

Problem: Image looks pixelated after resize

Solutions:

• Resized too large (can't add detail)
• Try smaller dimensions
• Use AI upscaling (external tool)
• Start with higher resolution original

Problem: Image looks stretched or squashed

Solutions:

• Enable "Maintain aspect ratio"
• Check width/height proportions
• Use Fit or Fill method instead of Stretch
• Verify original aspect ratio

Problem: Important content got cropped

Solutions:

• Use Fit method instead of Fill
• Try manual Crop for control
• Adjust dimensions to match aspect ratio
• Preview before downloading

Problem: File size still too large

Solutions:

• Resize to smaller dimensions
• Compress after resizing
• Convert to more efficient format (WebP)
• Reduce quality setting

Best Practices

DO:

• ✅ Maintain aspect ratio for photos
• ✅ Resize to exact display dimensions
• ✅ Keep originals as backup
• ✅ Preview before downloading
• ✅ Compress after resizing

DON'T:

• ❌ Enlarge images significantly
• ❌ Use Stretch method for photos
• ❌ Resize repeatedly (quality loss)
• ❌ Ignore platform requirements
• ❌ Skip preview step
