There are certain conventions and limitations you need to be aware of when working with Qlik Sense. For example: the maximum number of characters to use in names, descriptions, and expressions, as well as characters reserved for use by Qlik Sense only.
Max number of visualizations
The maximum number of visualizations there can be on a sheet is limited to the number of cells on a sheet, that is, 288 (24x12). The maximum practical number will be less than this because of the limited use for visualizations that are made up of only 1 cell.
Upper limits on name lengths
The following limits apply to the number of characters that can be used in various situations in Qlik Sense:
| Names (title, dimension, footnote...) | Max 255 characters |
| Descriptions | Max 512 characters |
| Expressions | Max 8,192 characters |
| Tags | Max 31 characters per tag and max 30 tags per master item |
| Text & image chart | Max 12,000 characters |
Naming dimensions and measures
If you use long names for your dimensions and measures they will be truncated and not the whole name will be shown in the label properties panel, instead “...” will be shown at the end. It is also recommended to avoid using some characters reserved for system purposes, as unpredictable results and errors could occur.
Avoid using the following characters in dimension and measure names:
| Colon | : |
| Equals sign | = |
| Left bracket | [ |
| Right bracket | ] |
| Left brace | { |
| Right brace | } |
| Dollar sign | $ |
Max number of characters in expressions
The maximum number of characters that can be written in a visualization expression is 8,192. If you attempt to build an expression with more than this number, the expression will be truncated.
