MOS:IMGSIZE

MOS:IMGSIZE

The guideline "MOS:IMGSIZE" refers to the recommendations and best practices for determining the size of images in Wikipedia articles. This guideline is part of the broader Manual of Style (MOS), which provides a comprehensive set of standards for writing and editing articles on Wikipedia.

Purpose

The primary purpose of MOS:IMGSIZE is to ensure that images are displayed in a manner that is visually appealing, accessible, and consistent across Wikipedia articles. Proper image sizing enhances the readability of articles and ensures that images complement the text without overwhelming it.

General Recommendations

• Default Size: Images should generally be displayed at their default size unless there is a compelling reason to adjust them. The default size is determined by the user's preferences and the display settings of their device.

• Avoid Fixed Sizes: It is recommended to avoid specifying fixed pixel sizes for images. Fixed sizes can lead to display issues on different devices and screen resolutions. Instead, use relative sizes or allow the image to scale naturally.

• Use of "thumb": The "thumb" option in image syntax is preferred as it allows users to click on the image to view it at full size and provides a caption. It also respects user preferences for image size.

• Contextual Sizing: The size of an image should be appropriate for its context within the article. Large images may be suitable for detailed diagrams or maps, while smaller images may be appropriate for simple illustrations or icons.

Technical Considerations

• Resolution and Quality: Ensure that images are of sufficient resolution and quality to be clear and informative at the chosen size. Avoid using low-resolution images that become pixelated when enlarged.

• Accessibility: Consider the needs of users with visual impairments. Images should be accompanied by descriptive alt text and captions to provide context and information for those who cannot view the image.

• Mobile Compatibility: Images should be responsive and display correctly on mobile devices. Wikipedia's mobile interface automatically adjusts image sizes, but editors should be mindful of how images appear on smaller screens.

Exceptions

There are situations where deviating from the general recommendations may be appropriate:

• Infoboxes: Images in infoboxes may have specific size requirements to fit the layout and design of the infobox.

• Galleries: In image galleries, it may be necessary to specify sizes to ensure a uniform appearance.

• Lead Images: The lead image of an article may be larger to provide a strong visual impact and context for the topic.
