The most accurate way is to weigh all-purpose flour on a kitchen scale. If you are measuring by volume, sift or whisk the flour first to break up clumps, then spoon it into the measuring cup and level it off. Do not scoop directly from the bag, which compacts the flour and can increase the weight by 20-30%.
