How many megabytes does 8X10 photo use?

An 8x10 photo typically uses around 2 to 5 megabytes in file size when saved in a high-quality JPEG format at 300 DPI (dots per inch). The size can vary based on the complexity of the image and the compression level used. For uncompressed formats like TIFF, the file size could be significantly larger, ranging from 20 to 30 megabytes or more.
