Any idea why there is a large gape between the top of the page and the figure as can be seen in the image below. I can understand that the figure is moved into the next page because space isn't enough but why is leaving the gape. Also, what is the best option to use for figures in between paragraphs to stop this issue from happening please? Many Thanks

\@fptop. – campa Aug 21 '20 at 16:58[ht]but the image you show shows them on a float page so presumably they could not be placed at all and drifted to the end of the document (or\clearpage) by default float pages are vertically centred so you get space above and below. – David Carlisle Aug 21 '20 at 18:36
