Could you please tell me how big the hotel advertising images are generally and what resolution they should be set to.

Hotel advertising pictures need to be set to 300dpi or above. If the raw material picture does not reach 300dpi, it will affect the printing quality.

The size should be based on the actual size. Set the unit in centimeters in PS. Do not In pixels.

If you design a picture with a side width of more than 1 meter and set it to 300dpi, the picture file will be very large. You can usually set the value according to 120-300dpi, which will not affect the quality, but the source The picture must be good.

PS The designed size and the actual printed size are based on a 1:1 ratio. The premise is that you must change the subsequent units to centimeters when creating a new file.
