[stunnel-users] stunnel overhead: Tunneling over stunnel - How does this affect MTU?

Hello, I am tunneling packets via stunnel using OpenVPN. I would now like to have an MTU in my tunnel where no fragmentation occurs. Hence my question: What overhead does stunnel introduce? Is the plaintext with a length one-to-one translated into the ciphertext? How large is the stunnel / TLS header? I look forward to any answer!
