Prints that have some keepsake value such as those that are due to be framed, displayed or mounted are generally printed on 180gsm to 200gsm options. It makes particular sense when you have many images to print as lower GSM often mean the paper is cheaper to buy.
Besides, what GSM is best for photos?
At least 260 gsm is recommended for A3+ prints and 310 gsm for A2 prints. The ideal paper weight for books that are printed double-sided is between 170 and 230 gsm, depending on page size. Watch out for “show through” where the image is visible on the reverse side of the sheet.
Herein, what is GSM for photo paper?
Naturally the same goes for photographic papers. The method that suppliers use to rate the weight of the paper is pretty simple. It is achieved by given the paper the weight per square metre or in short GSM (grams per square metre g/m²) to describe the paper matter density.
