2 Chainz is reported to be 6 feet 5 inches tall (65 inches, or about 1.96 meters) in multiple sources. If you’re asking about how tall a specific “2 chains” length is, here are common chain lengths and their approximate heights when worn:

• Short chains (casual/pretty close to neck): 16–18 inches
• Princess length: 18 inches
• Matinee: 20–24 inches
• Opera: 28–34 inches

If you meant something else by “2 chains” (for example, two chain links or a specific chain style), please clarify which measurement or context you’re after, and I’ll tailor the answer.
