What is the maximum number of custom fields on an object in Salesforce? And how does it vary per Salesforce Edition?

Salesforce editions

As like many limits in Salesforce, a lot of them vary by the type of Salesforce Edition you purchased. Strictly speaking, there are 4 editions

• Essentials

• Professional

• Enterprise

• Unlimited

The higher level of edition you have, usually the less limits you have. This is true for Custom Fields on any object in Salesforce.
