Sizing considerations

When knowledge workers create content in BMC Helix Knowledge Management by ComAround, they must consider the following types of content size limitations:

Article size limitations—These limitations apply to the article size and character count.
Field-specific limitations—These limitations apply to individual fields in articles, folders, and links.

Article size limitations

When knowledge workers create articles, they must consider limitations related to article size and character count. These limitations affect the ability to save articles, use machine translation, and access version history.

Important
These limitations apply per individual language version of an article. If the article is available in multiple languages, the limitations apply to each translation separately.

Category	Limit (per single language version)	Impact if exceeded	Details
Article size	1 MB	The article can't be saved.	The size of an article is calculated based on its text and formatting. Images and attachments are excluded from this calculation because they are stored separately. The actual size depends on character type and formatting, not the character count. For example, Chinese characters might consume more bytes than English characters. As a result, fewer Chinese characters can fit within the 1 MB limit.
			A single image or attachment must not exceed 350 MB.
			The combined size of all translations can exceed 1 MB, but each language version must remain within the 1 MB limit. For example, if an article is available in English, Swedish, and German, its total size can exceed 1 MB.
Machine translation	30,000 English characters	Machine translation is unavailable.	The limit applies to the total number of characters across all fields in an article. If exceeded, machine translation is unavailable, but manual translation remains possible.
Version history	31,940 English characters	The article can be saved, but it doesn't appear in the article history.	The limit applies to the total number of characters across all fields in an article. If exceeded, the article can be saved, but it is not included in the article history. As a result, version management is unavailable for this article version, and it can't be restored or refactored later on.

Important
The limit is measured in English characters. For other languages, the threshold may vary due to differences in character encoding.

Field-specific limitations

The following table lists character limits for specific fields in articles, folders, and links. If any of these limits are exceeded, the item cannot be saved. This rule applies even when other content size limits are within acceptable ranges. For example, if an article title is longer than 2,000 characters, the article cannot be saved. This restriction applies even when the total size of the article is within acceptable limits.
