Megapixels vs scale factors

Let's Enhance sells by output size (up to 256 or 512 MP) and scale (up to 16×) [1]. A 16× upscale of a 1000 × 1000 photo is 256 MP — far beyond most needs: a 24×36 in poster at a lab like Walgreens needs 5400 × 3600 px, about 19 MP [2]. Work out the size you need first; paying for 512 MP rarely helps.
