huge gaps between lines of my font and normal body text

I’ve cropped the font very tightly both sides dragging the bearings, then very tightly top and bottom using win ascent/descent and typo ascender/descender. It needs to be in around 72 pt to read clearly on a page, even though it’s not as tall as say 72 pt arial, but when I type a line, it allows space for the whole 72 pt, which leaves a big gap if I insert my font in the middle of body text. Even changing the paragraph/exactly x pt in MS WORD doesn’t fix it. Any ideas please?

Can you send me the font to take a look at?
