AutoFit Height ONLY not width

If it were up to me I wouldn't be making the final document in excel, but that's what I've been told must be used.

How would you change the layout though? The 4 lines I'm looking to change the hight are all different widths and need to take up the space already dictated by the current design. This is why i've added the same content in single cells (DP-DR). The cells all line up with the relevant rows so any height changes to them will also affect the main section.

I should probably also point out that the uploaded document only contains part of what is on the same worksheet in the final document. There's 100s of questions going down the page and ones further on require the layout to be different again. As this isn't a page that the user will edit directly the layout I have allows for the company branding to be added coherently throughout as well as with other pages.
