Garden Warblers are greyish brown above, with brownish white underparts, and have no distinctive features on their plumage. They can best be distinguished from other warblers by their fairly stocky body shape, their short, sturdy beaks, and fairly sturdy, greyish brown legs. Their beaks are grey, with a paler base to the lower mandible, and they have dark brown irises.
