In this section, you are given the option to explicitly define and Add new numeric custom field for your posts such as Price, Weight, Length, etc., depending on the needs of your posts. This field will be stored as a double floating point number.

You will also have the option to explicitly define and Add new text custom field such as Color, Fabric, etc. Again, this depends on the type of posts that you will have in your blog and if there is a need to specify a new field to make your post more readable or reader-friendly. This field will be stored as a varchar() field.

Read the Custom Fields page for more information on creating custom fields.
