https://help.salesforce.com/articleView?id=customize_recordtype_considerations.htm&type=5

To Create Record Types you can follow the below steps:

1. From the management settings for the appropriate object, go to Record Types.
2. Click New.
3. Choose Master from the Existing Record Type drop-down list to copy all available picklist values, or choose an existing record type to clone its picklist values.
4. Enter a Record Type Label that's unique within the object.
5. Enter a Record Type Name. The Record Type Name refers to the component when using the Web services API and prevents naming conflicts on package installation in managed packages.
6. For opportunity, case, lead, and solution record types, select a business process to associate with the record type.
7. Enter a description.
8. Select Active to activate the record type.
9. Select Enable for Profile next to a profile to make the record type available to users with that profile. Select the checkbox in the header row to enable it for all profiles.
10. For enabled profiles, select Make Default to make it the default record type for users of that profile. Select the checkbox in the header row to make it the default for all profiles.
11. Click Next.
12. Choose a page layout option to determine what page layout displays for records with this record type:

• To apply a single page layout for all profiles, select Apply one layout to all profiles and choose the page layout from the drop-down list.
• To apply different page layouts based on user profiles, select Apply a different layout for each profile and choose a page layout for each profile.

13. Click Save to edit the values of the standard and custom picklists available for the record type, or click Save and New to create another record type.
