We count pages like a book does – one leaf is two pages. Turn to the back of the book and check the page number of the last page and you’re good to go. If the book has only one-sided text, it depends on whether the order is for destructive or non-destructive scanning. If the order is for non-destructive scanning, we still require payment for both sides, as our scanning process does the two facing pages at once, therefore the time and labor are the same on our end. However we will not send you blank pages, we will remove them during the final processing. For destructive orders, you can count single-sided only.
