# Context
User can select a user preference for layout width "Fixed: Content will be a maximum of 1280 pixels wide." However, the Repository pages don't respect fixed layout. Most pages in GitLab respect fixed layout with the exception of:
* Issue Boards
* Merge request \> Changes tab
* All repository pages
* Probably some other pages
For the basic file/directory pages, a container width of 1200px is still pretty usable.
<table>
<tr>
<th>Fixed layout in GitLab (extra wide)</th>
<th>Repository page (extra wide)</th>
<th>Repository page (1200px container)</th>
</tr>
<tr>
<td>
{width=900 height=364}
</td>
<td>
{width="900" height="364"}
The Repository pages are information dense, but not so information dense that they need 100% of the width to be usable.
</td>
<td>
{width="900" height="375"}
1200px container is still a reasonable width for the Repository pages
</td>
</tr>
</table>
# Discussion
Is there any reason why we shouldn't support the Fixed layout for Repository pages?
