Has Anyone Made Posters From Renders???

I plan to do an image of a toddler sized mermaid for my new grand daughters bedroom. My daughter is doing an under the sea theme for her room.

I have no clue how many pixels I need to save my render out to for the poster dimensions. I do know a higher dpi is good, such as 300.

Any help in figuring this out would be greatly appreciated.

I found this on one search... 

Standard Poster Size The most commonly used sizes for posters are 18” x 24”, 24” x 36” and 27” x 40”. These are the most requested sizes at SLB Printing, Inc. for common posters that print on our wide format latex inkjet printers. By no means is this the complete list of sizes.

And I found this on another search...

Print Size vs. Image Size Chart

PRINT SIZE 100 DPI 300 DPI
In Inches Image Dimensions in Pixels Image Dimensions in Pixels
8 x 12 800 x 1200 2400 x 3600
11 x 14 1100 x 1400 3300 x 4200
12 x 18 1200 x 1800 3600 x 5400

    The math is very straightforward: multiply the number of inches by the DPI. If you're going for 300 DPI, multiply both of your dimensions by 300 to get, for example, 5,400 x 7,200 for an 18x24" poster.

    Depending on the size of the poster and its viewing distance you wont need 300DPI. The bigger the poster you could use 100DPI and, unless you are standing right up against it you wont notice the difference. The Billboards that are used for advertising on buildings or beside the road can be down to 4DPI.

    In practice, it might be necessary to use an upscaling tool to get a good print result for a large poster. An A1 sized print (~84x60cm/~33x24") wouldn't be unusual for a poster, but the ~10,000 x 7,000 pixel resolution for a 300 DPI print would make for an extremely demanding render for most GPUs to do at full resolution.

    I think DS has a pixel limit on the images anyway. Not quite sure what it is, but 10,000x7,000 rings a bell.

    I made an 18"x30" digital print on canvas over a decade ago. the file was 5400x9000 pixels. It's still hanging on my wall.

    I never did it, but I remember sites offering the service having systems in place to check if a picture is good enough (likely based on the resolution) so it should be easy to test what resolution they find good enough for a poster (by upscaling a render or a creating a blank picture at various resolution).

    @Faeryl Womyn: If you decide to go on and print it, could you share your experience here?

    I've done a lot of them.  No I don't try to do the actual render to full size.  I pick a good size at 300 dpi- say 10000 pixels max one side. ( I do that for ALL of my artowrk these days as I license most it/it needs to be a good repro resolution for many applications/sizes.) Then using a program like Gigiapixel you can make that finished piece HUGE... and I mean like billboard huge.. and yes most of the time posters are more like 150 dpi, even high quality ones.  Depends on the printer/company making the poster.  Check or ask for the printer's specs and also often they will let you know if your art wil not reproduce well enough at the size/res it is currenrtly.

    For a poster that is going to be viewed from a distance 200 PPI  is probably adequate.

    Not a direct answer to your question, but having done a lot with publishing ... I would recommend finding the company you want to do your printing with first ... then get their guidelines / requirements. It should be specific on the size of the image, the amount of bleed necessary, desired DPI, etc. If your computer can handle the size, I would render it as large as possible ... and yes, you can turn off the limits and render much larger than 10,000 pixes. I have done a few images ( cartoony and rapidly rendered ) at 30,000 pixels on the long edge.

    PS. They might also want the image in CMYK format rather than RGB ... that issue is becoming less and less common to deal with as equipment improves its abilities to print RGB.

    Thank you all for the information and will show my daughter, it's just a poster for my grand daughters room, not something that will hang in public, but I do want a decent resolution for it.

    I will double check on the number of pixels Daz will render. The lower DPI will be useful for how long it takes to render and if my computer will be able to handle it.

    Yes I will definitely post my results.

    As for how it will be printed, I have to ask my daughter again, most likely will go to a local store, cause I don't think they have a printer for posters.

    I have this thread bookmarked so I don't lose it.

    Oh I forgot to mention their computers are way better then mine and they do have photoshop.

    I've had large prints made to sell at cons, and most printers require 300 ppi, so all of my client renders are 5000 pixels or larger because many of my authors print large cover shots or just the art for their book events.
