Right. One pixel per inch. Over 5000 inches wide. When printed at 17 inches is 300 dots per inch. 

Was that a test or something?

I got a photo one time that was 1 pixels/inch. Or cm. Still was plenty big enough to print 17 inches wide.

I'm sorry. So, open the photo with whatever you used to determine that it's at 96 dpi. Or hell email it to me and I'll just tell you what you have, really.

Wouldn't that be awesome? My book cover that big for everyone to see?

jrzy didn't give the right answer. The image could be 3 million pixels in width, big enough to print on the side of the MetLife Stadium, and be described as 96 dots per inch.

Just like how in my example, we don't know how far it is to the store by knowing only miles per hour, we can't know how big the image is by knowing only dots per inch. It's an incomplete formula, and it's an ass backwards way of describing image size because even when you have the rest of the formula you have to do the math.

Exactly. When people start throwing math equations my way, my brain automatically shuts off. I am a bona fide math-o-phobic.

It's going to be for both a hardcopy book cover and an e-book.
 
 
Mostly, I just wondered if an image at 96dpi sounds like she sent it raw without trying to size it or not. That's why I just asked if she could send the raw original—-just in case. That way I have it, and can work with it accordingly.
 
 
Thanks.....and thanks everyone else too!

i didnt do the math ( too lazy to open a calculator). it just seemed that there were easier ways to answer A's question. kinda like jrzy did.

That explains it.

What Scott is really saying is, it's the total dots that count, not the dots per inch.  And it's not really dots until it's printed, it's pixels. 

Imagine this scenario.......

Me: How far is it to the store?

You: One mile per minute. (sounds a lot like dots per inch huh?)

Me: Hm. Okay. But it seems like some of the formula is missing. I now know how many miles I'll cover in a minute, but I don't know how many minutes it will take. When I know how many minutes it will take, I can figure out how far it is to the store by doing the math. 

So, if we know only that the image has 96 pixels in an inch, but we don't know how many inches the image is, we really have no idea how large it is. If, for example, the image is 96 pixels per inch and has a total of 1344 pixels in width, the image is 14 inches wide. (1344÷96=14) If we decide to print this image, or display it, at only 7 inches in width, without doing anything else we double the pixel count. (1344total pixels ÷ 7inches = 192 pixels per inch.)

The bottom line is, the total pixels is what matters. If, for example, the image is 3000 pixels wide, at 300 pixels per inch, and we print at 300 dots per inch we can print an image 10 inches wide.  (3000 pixels, divided by 300 pixels per inch, equals 10 inches. 

Dots per inch or pixels per inch are essentially meaningless until you go to print. If this has to do with an e-book that will never be printed, whoever is requiring 300 dots per inch needs to go back to school. 

Oh shoot. I've confused myself.

Thought I'd try that one out. Didn't work? I'll tell my friend in California who teaches photography at a college out there, and is always trying to find better ways to get students to understand resolution.

I just asked her to send the original, unsized file......and yes, hopefully.

This is what we call a "Ranch" problem. Rancher Bob has a 100 acre ranch with 20 cows per acre. Rancher Tom has a 50 acre ranch with 50 cows per acre. You have 96 cows per acre. Who has more cows?

96 is for viewing on the innertubes. if printed, it will be pixelated or blurry when printed.
ask the person who did it to resize from the original for 300 dpi.I hope her original is 300 or better.

My cover art has been sent.
 
The image is at 96 dpi. I must submit it at 300 dpi.
 
Is this going to work? Is 96 dpi what an original image usually is?   Or does it sound like it's been sized?
