See regionprops(), in particular BoundingBox and Area .

Notice, though, that your blobs are not aligned vertically or horizontally. You might want to ask regionprops for the Orientation and then imrotate() the blob by the negative of that in order to align it and then regionprops() the result to get the height and width.
