Why my subplot imshow not equally.

Hi, I have a problem. My subplot imshow not equally even though image size is equally.

k = 1;
for i=1:2:col_size
    m = 1;
    for r=1:rml
        n = 1;
        for c=col(i):col(i+1)
            letter(m,n) = ime(r,c);
            n = n + 1;
        end
        m = m + 1;
    end
    if size(letter,2) >= 6 && size(letter,1) <= 90
        subplot(1,(col_size/2),k);
        imshow(letter);
        k = k + 1;
    end
    clear letter;
end
