It measures just short of 4" tall, 3" side-to-side on the base, and 4" from back to front of base. It weighs 1 lb, 2.4 oz.  It was painted black at one point but the paint is now cracked to show an orange interior. The base has damaged but present felt for placement on a surface without damaging the surface.  The thermometer works as seen that it shows 70 Fahrenheit in the house.  When found in an estate sale cool basement, it showed 60 Fahrenheit.  The one issue of note is that the front glass has been pushed back from the grooves on the top portion - see last listing photo.  To bring if fully back, it will need this glass to be either replaced or moved forward to the original grooves intended for it.
