Change Your View with Display Density Settings
Where: This feature applies to Lightning Experience in Group, Essentials, Professional, Enterprise, Performance, Unlimited, and Developer editions. Density changes don’t apply to Communities or the Salesforce mobile app.
Why: The Compact setting, which has labels to the left of fields and less space between page elements, fits 30% more fields on the page.
Comfy has labels on the top of fields and more space between page elements. It’s similar to previous versions of Lightning Experience.
Both settings include some darkened text colors to go beyond the color contrast requirements of the W3C’s WCAG 2.0 AA, the industry standard for web accessibility. Existing orgs have Comfy as the default setting. New orgs created after Winter ‘19 is released might default to Compact. Salesforce continues to improve the experience and expand to more page elements in future releases.
How: From Setup in Lightning Experience, enter Density Settings in the Quick Find box, and then select Density Settings. The org default setting applies, unless a user changes it from their profile menu. You can’t override a user’s display density preference.
Salesforce notifies all Lightning Experience users of the new setting with in-app assistance.
