You could use regionprops to find the major axis length. Or did you need the length of the object in the y-direction? What do you mean by height?

Img = imread('segemented cup 1.jpg');
imshow(Img)

size(Img)

ans = 1×2

375 309

rp = regionprops(imbinarize(Img),"MajorAxisLength")

rp = struct with fields:
    MajorAxisLength: 124.5538

Try regionprops and ask for Bounding Box of your binary, segmented image.

props = regionprops(mask, 'BoundingBox');
bb = vertcat(props.BoundingBox); % In case there is more than one blob in the image.
heights = bb(:, 4); % Height along the y direction.
