Purple peppers, also known as Korean purple peppers, borrowed their unique color from breeding with ornamental pepper varieties. However, size-wise, they typically fit into the same categories as their colorless kin.

Jalapeño, the most common hot pepper, grows up to 2-3 inches in length and about 1-2 inches in width. Korean purple peppers, which are often classified as hot peppers, usually fall into this size range. Their length might reach up to 3 inches, with a width of about 1-2 inches.

Serrano and Thai peppers, which are also frequently purple, usually grow slightly smaller than jalapeños, ranging from 1.5 to 2.5 inches in length and about 0.5 to 1 inch in width.

Sweet Peppers

Sweet purple peppers, like Bell peppers, are typically longer and bulkier than their hot counterparts. A ripe bell pepper can range from 3 to 4 inches in length and about 2.5 to 3 inches in width at the top.

For instance, the Purple Beauty Bell Pepper grows up to 4 inches long and 3 inches wide, while the Purple Rain Bell Pepper can grow slightly larger, reaching 4 to 5 inches in length and 3 to 4 inches in width.
