This is a sort of guide on canvas sizes, inches, dpi and pixel x pixels.
when it came to canvas sizes, I always kind of assumed that inches belonged with dpi and pixels were just pixels and that everyone knew that; but i read a whole bunch of comments on a tumblr blog where someone asked about canvas sizes, and SO MANY people were replying with things such as, "4000x4000 px at 300 dpi" or "2000x2000 px at 200dpi".
and I guess not everyone quite understands what dpi's really used for xD.
DPI = Dots per Inch. It means how many dots will be printed per inch.
DPI is actually used for printing purposes. It shows the printer how much pixels to print per inch, literally. A common printer (at home or even at a lot of printing stores) at best prints at 150dpi most of the time actually; there are some super duper great printers that can print REALLY fine that can go up to ...apparently a lot more xD; #dpi, so that's why everyone usually suggests saving your project at 300dpi; most printers are fine with 300dpi, because anything above that is a little overkilling it.
so say I have a canvas at 5400 x 3600px, it literally means that I have a canvas that can be printed on a 18 x 12 inch paper at 300 dpi. If I have a 5400 x 3600px canvas at 200dpi, that pixels of the canvas don't change, but the inches on the physical paper can change to 27x18 inches when it comes to printing it. The canvas pixels aren't going to change just because you have it at 200dpi, so putting 200dpi, 300dpi or even 800dpi, it isn't going to make a difference digital canvas-wise. If you say something like "5400 x 3600px at 300 dpi", it's the same as saying "5400 x 3600px at 18 x 12 inches.". See how they don't mix?
Either put down how big it is in pixels (because you don't REALLY need the 300dpi if you're not printing it out), or if you have an intention of printing it out, do it in inches (or cm, if that's what you're used to) with a dpi attached.
Even photoshop makes it clear - The pixels are in the "Pixel-dimention" section, and the inches/cm/mm/etc and dpi is under the "Document-size" section.
TL;DR: Canvas inches and dpis are for physical prints only; Pixels are digital, so they don't mix with dpis or inches, etc. Digital and physical don't mix in a way that would make sense. Please don't say "2000 x 2000px at 300dpi"~ @_@;
I hope I made sense and cleared up some misconceptions about dpi and canvas sizes . ….and i hope i didn't make a mistake here hahaha;;;.
damn, i wrote a lot; sorry, bad habit D:~!
edit: if you're a math-kindda person, you can also look at this mathamatically:
12 x 18inch at 300dpi =
12 x 300 dpi = 3600pixels
18 x 300 = 5400
therefore 12 x 18inch at 300dpi = 3600 x 5400pixels
and that's how you get the pixels vs inches + dpi.

A little update
Hey guys~ Wow, long time no see... I wish I had really good news and life is awesome, but my luck hasn't really been great haha... So...I have stage 4 Fibrosis Sarcoma cancer.....Doctor says I have about a year, year and a half left, so.. ...I'm not really sure what to say tbh. I've been cracking jokes on twitter but, well, tbh I'm pretty stressed haha... though, I'm already pretty nihilistic so I really just need to get over my mortality haha...easier said than done tho xD. Uhh....well, I guess I don't have to worry about recycling anymore, my emission's about to get cut real short lmao. Still gotta crack jokes or it's just sad man lol that's all I have to say right now. I appreciate all the support on twitter and people becoming my patron is just so sweet, thank you guys so much. I apologize my condition might only get worse before it gets better though, I still have a lot of pain problems right now actually...i think that's the worst part of this though, is the pain. god. I'm so

Got a Facebook and a new Youtube
Hi guys :D. I figured I'll just post all my social media on here today :). I'll be super happy if you guys follow any one of them that's easiest for you :D. dA's still my oldest one, so thank you guys so much for all the support over all the years :hug: Youtube Facebook Instagram Tumblr I've started recording timelapses, and a lot of people have asked for youtube videos on Instagram and it gives pretty great resolutions too, so I've started uploading there :). I also finally started a facebook. My second try cause after I created the first one last year, I started doubting I was good enough to have one so I deleted it. haha i regret it
I am trying to design a Dakimakura of 20x54"...I keep trying to set the physical size for a highres print, but can't get the physical size I want. Any chance you can help? I use Autodesk Sketchbook Pro, but the settings are very similar to Photoshop. I have a menu to image size and a menu for canvas size.
This is fair, but I think people are entirely justified to say "X by Y pixels at Z DPI" because you can't fix DPI once an image is set (as in if you want to print at a certain DPI, you'll just have to decrease the size of the image if DPI is too small). So When people make that statement,they are doing creating a safety net by assuming that the asking artist may be interested in printing. Also, there is a direct correlation between DPI and inches, so it actually doesn't make a difference to change inches or DPI on sai since it automatically converts it.
sorry if this is a noob question but is the resolution section on sai when making a new canvas the same as DPI? i feel pretty nooby asking this and i've been using SAI for a year hehe -nervously sweats-
the units used for size should be marked down on SAI. i haven't used SAI in a while though so I can't remember if it had inches, but it should always say whether it's in pixels or inches. If it's in inches, there will always be a DPI section for you to input. If it's in pixels, dpi is not necessary.
Hmm. Seems interesting. Mind if I ask you, but what is the average size of canvas for something like a tutorial? Those long deviations? Since I'm wondering if I can use that canvas size for my closed species.
My printer only prints at 600 dpi, it's a newer HP Photosmart, so I'm getting overkill regardless. Why would I print an image at 3600x5400 and have every 1 "dot" end up being printed as 4? Well the answer is quite simple really: because my computer sucks monkey balls and wouldn't be able to handle 7200x10800 pixel images, lmao.
I've been looking for something like this! what are good dementions for a webcomic? usually i scan stuff in, but i want to start drawing digitally - but whenever i do the pictures end up pixelated when i zoom in a bit, and i can't seem to do any proper detail. (using paint tool SAI btw) i thought it was something to do with a low DPI setting but apparently not...?
