Getting comfortable

Josh picked up his, now tiny in his hands, phone and started to type:

The house I live in was built for someone my size.

As soon has he hit enter the room and house started to grow around him as he felt a little dizzy. His room's ceiling lifted from his back and continued to lift. Eventually after half a minute he was able to stand up fully and still had a foot of space. Lastly, he started to type one more thing into his phone:

All my clothes will now fit me.

Again as soon as he hit enter the clothes in his chest of drawers grew and started to crack the wood. Shortly after the panel fell from the front of the top drawer. He swiftly picked some clothing and got dressed. He reached for the doorknob and opened it.
