How to Select Export Size in Grid Tool
2026-01-15
Grid Tool provides flexible export size options, allowing you to choose the most suitable resolution for your grid posters based on your specific use case. This article provides a detailed guide on how to select export sizes and understand the different options available.
What is Export Size Selection?
Export size selection is a feature that lets you choose the maximum dimension (width or height) of your exported grid poster before generating the final PNG image. The system automatically calculates the complete dimensions based on your grid's aspect ratio and orientation.
Export Size Features
- Four preset sizes: 1980px, 1280px, 1024px, and 768px (maximum dimension)
- Automatic calculation: Complete dimensions calculated based on aspect ratio
- Orientation-aware: Different calculations for landscape and portrait layouts
- Real-time preview: See the selected size before exporting
- Quick selection: Easy dropdown interface for size selection
Available Export Sizes
Grid Tool offers four export size options:
Size Options
-
1980px (Maximum)
- Highest resolution option
- Best for: High-quality displays, printing, professional use
- Example: 1980 x 1320 (for 3:2 landscape)
-
1280px (High)
- High resolution option
- Best for: Desktop displays, large screens, detailed viewing
- Example: 1280 x 853 (for 3:2 landscape)
-
1024px (Medium)
- Medium resolution option
- Best for: Standard displays, web sharing, general use
- Example: 1024 x 683 (for 3:2 landscape)
-
768px (Standard)
- Standard resolution option
- Best for: Mobile displays, quick sharing, smaller file sizes
- Example: 768 x 512 (for 3:2 landscape)
How Dimensions Are Calculated
The export size represents the maximum dimension (width for landscape, height for portrait). The other dimension is automatically calculated to maintain the grid's aspect ratio:
- Landscape orientation: Width = selected size, Height = width ÷ aspect ratio
- Portrait orientation: Height = selected size, Width = height × aspect ratio
How to Select Export Size
Step-by-Step Guide
- Locate the size selector: Find the export size dropdown in the top right of the preview area
- Click the dropdown: Click on the current size display (e.g., "1980 x 1320")
- Choose a size: Select from the available options in the dropdown menu
- Confirm selection: The selected size is immediately applied
- Export: Click the "Export PNG" button to generate the image at the selected size
Visual Indicators
- Current selection: The selected size is displayed in the dropdown trigger
- Dropdown menu: Shows all available sizes with calculated dimensions
- Checkmark: The currently selected size is marked with a checkmark
- Size format: Displays as "Width x Height" (e.g., "1980 x 1320")
Understanding Size Calculations
Example Calculations
For a 3:2 aspect ratio in landscape orientation:
- 1980px: 1980 x 1320 pixels
- 1280px: 1280 x 853 pixels
- 1024px: 1024 x 683 pixels
- 768px: 768 x 512 pixels
For a 3:2 aspect ratio in portrait orientation:
- 1980px: 1320 x 1980 pixels
- 1280px: 853 x 1280 pixels
- 1024px: 683 x 1024 pixels
- 768px: 512 x 768 pixels
Different Aspect Ratios
The actual dimensions vary based on your grid's aspect ratio setting:
- 16:9 (HD): Wider format, more pixels in width
- 4:3 (TV): More square format
- 1:1 (Square): Equal width and height
- 21:9 (Ultrawide): Very wide format
Use Cases
Scenario 1: High-Quality Display
Use case: Creating posters for high-resolution displays, professional presentations, or printing.
Recommended size: 1980px
Why: Maximum resolution ensures crisp details and professional quality suitable for large displays or print media.
Scenario 2: Web Sharing
Use case: Sharing posters on websites, social media, or embedding in web pages.
Recommended size: 1024px or 1280px
Why: Good balance between quality and file size, loads quickly while maintaining visual quality.
Scenario 3: Mobile Viewing
Use case: Posters primarily viewed on mobile devices or for quick sharing.
Recommended size: 768px
Why: Smaller file size for faster loading on mobile networks, sufficient quality for mobile screens.
Scenario 4: Storage Optimization
Use case: When storage space is a concern or you need many variations.
Recommended size: 768px or 1024px
Why: Smaller file sizes reduce storage requirements while maintaining acceptable quality.
Best Practices
Size Selection Tips
- Consider your audience: Choose size based on where and how the poster will be viewed
- Balance quality and size: Higher resolution means better quality but larger file sizes
- Test different sizes: Export at different sizes to find the best balance for your needs
- Default is maximum: The default 1980px is suitable for most professional use cases
Workflow Recommendations
- Design first: Complete your grid design before selecting export size
- Preview check: Review the preview to ensure everything looks good
- Select size: Choose the appropriate size for your use case
- Export: Generate the final PNG image
- Verify: Check the exported image quality and dimensions
File Size Considerations
- 1980px: Typically 500KB - 2MB depending on content
- 1280px: Typically 300KB - 1MB
- 1024px: Typically 200KB - 800KB
- 768px: Typically 100KB - 500KB
Note: Actual file sizes vary based on image content, cell count, and compression.
Export Size vs. Display Quality
Resolution Guidelines
- Retina/High-DPI displays: Use 1980px or 1280px for best results
- Standard displays: 1024px is usually sufficient
- Mobile displays: 768px provides good quality with smaller file size
- Print media: Use 1980px for best print quality
Quality vs. Performance
- Higher resolution: Better quality, larger file size, slower loading
- Lower resolution: Smaller file size, faster loading, slightly lower quality
- Sweet spot: 1024px-1280px often provides the best balance
Frequently Asked Questions
Q: Can I export at a custom size?
A: Currently, Grid Tool offers four preset sizes. For custom sizes, you can export at the maximum size and resize using image editing software.
Q: Does export size affect the preview?
A: No. The preview always shows the full design. Export size only affects the final exported PNG file.
Q: Can I change the export size after designing?
A: Yes. You can change the export size at any time before clicking the export button. The size selection doesn't affect your design.
Q: Which size should I use for Jellyfin/Emby?
A: For media libraries, 1280px or 1980px are recommended for best quality. Most media libraries can handle these sizes well.
Q: Will changing the size affect image quality?
A: The exported image quality is always high. Higher sizes provide more detail, while lower sizes may have slightly less detail but are still high quality.
Q: Can I export the same design at multiple sizes?
A: Yes. You can export multiple times with different size selections. Your design remains unchanged, only the export resolution changes.
Tips for Different Use Cases
For Media Libraries (Jellyfin, Emby, Plex)
- Recommended: 1280px or 1980px
- Reason: Media libraries benefit from higher resolution for better display quality
- Note: Check your media library's recommended poster dimensions
For Social Media
- Recommended: 1024px
- Reason: Good balance of quality and file size for social platforms
- Note: Some platforms may resize automatically, but starting with good quality helps
For Web Embedding
- Recommended: 1024px or 1280px
- Reason: Fast loading with good visual quality
- Note: Consider using responsive images for different screen sizes
For Quick Sharing
- Recommended: 768px
- Reason: Small file size for quick uploads and sharing
- Note: Quality is still good for most viewing scenarios
Conclusion
Export size selection is a simple but important feature that helps you optimize your grid posters for different use cases. By understanding the available sizes and their best use cases, you can choose the perfect resolution for your needs. Remember, you can always export at the maximum size first and resize later if needed, but selecting the right size from the start saves time and storage space.
