"Sizing Up" is an art/alt rock track about getting constant critique and pressure from others and choosing to outgrow it. Set in a dim bedroom lit only by a lamp, with someone creeping outside the door, the song captures the moment you realise you need to break free. With cutting guitars akin to Muse, Fiona Apple-esque vocals, and a synth pulse inspired by New Order, it's a cathartic release captured in song.
