Hi Zoe, Thanks for contacting us! Using the Crop tool is correct when trying to get your image to exactly fit different paper sizes. All that’s required is to choose the area you want to keep on your image (by dragging around the crop area which appears on your image when using this tool) and then click the Apply button. No other scaling is required, as the crop tool exactly sizes your image to fit the paper. Let us know if you have any further questions!
