ImageField.width_field

Name of a model field which will be auto-populated with the width of the image each time the model instance is saved.

ImageField instances are created in your database as varchar columns with a default max length of 100 characters. As with other fields, you can change the maximum length using the max_length argument.

The default form widget for this field is a ClearableFileInput.
