Media Library Modal Dimensions

Media Library Modal Dimensions adds width and height settings to every Media Library widget so the modal dialog can be sized to the content it displays — per field, without custom JavaScript or global theme overrides.

Some Media Library fields benefit from a wider or taller picker (image galleries, video browsers) while others are fine at the core defaults. This module lets each field pick its own.

Features

• Per-field control of the Media Library modal's width and height.
• Settings exposed through Drupal core's existing widget settings UI — no new admin pages, no custom routes, no permissions to manage.
• Accepts percentages and pixel sizes (integer or decimal) plus auto
• Forward-compatible wrapper pattern that survives expected core refactors of MediaLibraryWidget (see core issue #3127867).
• Works with any field on any entity type that uses the Media Library widget — content types, paragraphs, custom entities.

Installation

Install as you would normally install a contributed Drupal module. No additional configuration step is required after enabling — the new settings appear automatically on every Media Library widget.

Configuration

1. Go to Structure → Content types → [your content type] → Manage form display (or the equivalent screen for any entity that uses a Media Library widget).
2. Click the gear icon next to a field that uses the Media library widget.
3. Set Media Library dialog width and/or Media Library dialog height to one of:
   • A percentage — for example 75% or 95%
   • A pixel size — for example 900px or 1200px
   • auto
4. Click Update, then save the form display.

Leave either field empty to keep Drupal core's default of 75%.
