my client wants to print this photo on a poster of 10x4 meter board. i had all the files or I can make a new one too. please tell what should be the resolution and pixels etc.

  • Ask the printer. Guess: 50 or 100 dpi – Digital Lightcraft Aug 3 '17 at 12:14
  • The more the merrier. Make it 300 pixels per inch, multiply 300 by however many inches are in 10 meters, then do same for height. That's your target size. I hope your photos are high resolution. – Webster Aug 3 '17 at 13:21

We cannot answer this.

The only person who can is the one printing it.
