About Keynote Image Sizes
Confirm the slide size in the Document sidebar before resizing. Apple lets you enter a custom size when a preset does not match the target screen.
Scale to Fill covers the slide but may crop the image; Scale to Fit preserves the full photo but can leave space. Preview the composition for both.
