A door brace (10) comprising: an engagement member (12) comprising a bottom flange (14) comprising one face comprising a textured surface (14a) to engage with a door (34); an angled leg (20) comprising a first section (22) hingedly connected at one end to the wall and a second section (23) extending from the first section at a first angle, the leg being movable between a stowed position and an extended position in which the first section makes a second angle, larger than the first angle, to the wall; an engagement foot (26) pivotably mounted on a mounting element (24) having an adjustable length; and a hinge stop configured to prevent the leg moving beyond a maximum extended position. Wherein, in an extended position, the second section of the leg extends at a third angle to the wall equal to the difference between the second and first angles and the engagement foot causes a clamping force to be applied to the door.
