Because the standard printing resolution for photographs is 300dpi you can calculate the approximate megapixels needed for each image size. Multiply the image height and width by 300 to get a rule of thumb for pixels needed for that print. For example, and 8x10 becomes 2400x3000 pixels. Next multiple the pixel dimensions together. For this example, that means 2400x3000 becomes 7.2 million. That is the number of megapixels needed to record a print quality 8x10 image.

Wallet 750x900 pixels .7 megapixels
4x6 1200x1800 pixels 2 megapixels
5x7 1500x2100 pixels 3.1 megapixels
8x10 2400x3000 pixels 7.2 megapixels
 
In the real world, you can usually get away with far fewer pixels than 300dpi/ppi might suggest. I have printed good A3 prints from a 6MP camera and A4 from a 3MP one. I wouldn't really want to go much bigger than that on glossy paper but on canvas, it could work, especially with a simple subject like the trees.
 
Nice one lads thers some kinda wall netween togs and printies grrrr
 
I'd say with that image on canvas you might be able to get away with an A3, don't forget you need additional real estate to form the wrap.

A good quality and professional canvas printer should be able to look at the image for you and advise - after all they will be taking the risk on it if you want to go bigger and were not happy, and would want you to print as large as possible to make as much money from you. That should cause them to make a sound recommendation.

But they would want to make that recommendation after looking at the hi-res file I'd suggest.
 
Hey meonshore thankyou for that. What a great community talk tog has. 5 STARS
 
Hi John,

The confusion might be because you can get away with a much bigger print on canvas than you can with paper. Paper is much finer so you need the higher resolution, 300DPI is typical of most printers, with canvas however you can go much lower as the canvas isn't as fine as paper, I've printed several large canvases at 120DPI and they look excellent, you should comfortably be able to produce an A3 canvas with you 3MP image. If the print company isn't sure then I wouldn't spend my money with them and find one that is.

Yip. I've printed A2 from the 30D (8.2 MP), and I'm confident I can go even larger. I also printed A4s from my old Minolta Dimage 7i set at 2 MP (I was running out of memory card space) and they were fine. The old caveat about normal viewing distance obviously applies, and I'm pretty sure lens quality plays a part in this too.

Ok how do I know how many dpi I have.

What is the pixel size of your image what quality did you save it at in what software (all matter - dpi is a bit of a red herring)

What size canvas would you really like it printing at?
