1. Platform:
* Webtoon Platforms: Each platform has different guidelines. Check the specific requirements for the platform you're using. Some common examples:
* Line Webtoon: Recommends 720px x 1280px for vertical thumbnails.
* Tapas: Recommends 720px x 1280px for vertical thumbnails.
* Lezhin Comics: Recommends 720px x 1280px for vertical thumbnails.
2. Intended Use:
* Social Media: If you're using the thumbnail for social media, consider the platform's recommended image sizes.
* Website: Make sure the thumbnail fits well on your website layout.
* Print: If you plan to print the thumbnail, you'll need a higher resolution to avoid pixelation.
3. Your Style:
* Simple Design: A simple thumbnail may require a lower resolution.
* Detailed Design: A complex thumbnail with lots of details will benefit from a higher resolution.
General Recommendations:
* Vertical Thumbnails: 720px x 1280px is a common and widely accepted resolution for webtoon thumbnails.
* Horizontal Thumbnails: If you're using a horizontal thumbnail, aim for a resolution that maintains a similar aspect ratio to the vertical format.
Calculating Pixels over cm:
* Pixel Density (DPI): The higher the DPI, the more pixels are packed into a given space, resulting in a sharper image. A common DPI for webtoon thumbnails is 72 DPI.
* Formula: You can calculate pixels per centimeter (PPC) using the formula:
* PPC = (DPI * cm) / 2.54
Example:
* Thumbnail Size: 720px x 1280px
* DPI: 72 DPI
* Width in cm: (720px / 72 DPI) * 2.54 cm/DPI = 25.4 cm
* Height in cm: (1280px / 72 DPI) * 2.54 cm/DPI = 45.1 cm
* Resolution in pixels over cm:
* Width: 720px / 25.4 cm = 28.35 px/cm
* Height: 1280px / 45.1 cm = 28.38 px/cm
In Summary:
* Follow platform guidelines: Check the specific requirements for the platform you're using.
* Consider your intended use: Choose a resolution that fits your needs.
* Experiment: Try different resolutions to see what works best for your style and design.
