## Por Que e Quando Desempenhar Esta Tarefa

The following figure shows how the variables for the different Apple iPhone 5 options are set to different widths.Figura 1. Page for iPhone 5 catalog item with variables of varying widths

A default width size cannot be set or does not apply to the following variables:

* The break, container end, container split, container start, and label variables.
* Any variable placed in a container with two-column layout.
* A variable set with a two-column layout.
* Any variable that is created with a custom width set in the Variable width field on the Variable form. For details, see [Create a service catalog variable](https://servicenow-prod.fluidtopics.net/9PsGFhRWHhit~RhUTlhtcg "Create service catalogs variables to gather information from users ordering a catalog item, for example, to ask users which options they want for the item."). The custom width for the variable overrides the default width set for the variable type.

Nota:  
Custom variable widths are not supported in either Mobile or Service Portal.
