Sandpipers have long bodies and legs, and narrow wings. Most species have a narrow bill, but otherwise the form and length are quite variable. The bills are sensitive, allowing the birds to feel the mud and sand as they probe for food. Sandpipers range in size from the Least Sandpiper, at as little as 11 cm (4.3 in) in length, to the Eastern Curlew, at up to 66 cm (26 in) in length.
