Good Morning Bing,

Problem is that each time the title undergoes a smaller
font size change,
the chart actually changes position within the chart area
by moving up.

Also any labels i've placed in the chart area also
changes position and move
up as well.

Anyone have any ideas why and how to stop this?

well, afaik this is because Excel automatically arranges
all elements within a chart so that every element has the
max size. So if e.g. the chart title becomes smaller,
excel makes the chartarea larger...

I think you could stop this by using the

AutoScaleFont Property

for each element within the chart... e.g.

Selection.AutoScaleFont = False

Best
