How do I find the dpi on an online image? I need photos that have a dpi of 300 or higher

I do right click on the image but then what?

1. Right-click on the image file and click Properties

Right-click on the image file and click Properties at the bottom of the menu. In the Properties menu, click the Details tab. Scroll down to the Image section of the menu; you'll see two values that give you your image's DPI: Horizontal Resolution and Vertical Resolution

2. And note, this will just tell you how many dots there are.

The image can be any physical size you want, so the DPI will depend on how big you want to physically make the image.

E.g. a 1920x1080 image will be above 300 DPI as long as it's not blown up larger than 6.4 in x 3.6 in.

If you know how large you want the photo to be, just multiply each dimension by 300, and look for photos larger than that resolution.

5. I have failed several times doing this. I must be doing something wrong. I'll get back to this

a bit later and try again.

I know your directions are fine, it's probably just me making a dumb mistake somewhere...thanks...and I'll let you know when I figure out what I'm doing wrong...

3. All you really need is the pixels in width and height.

So if you have an image that is 800 pixels wide by 1200 high, and you are going to make a 10 inch wide print, all you need to do to calculate the final DPI (dots per inch) is divide (800 pixels) by (10 inches) and your final print will be 80 pixels/inch. You can use dots and pixels interchangeably.

I'd be really shocked if you really need 300 or higher, I'll bet 150 would be just fine for 99.9% of the population of eyeballs of humans.

7. well, this is an art book so my instinct is to get the 300 to do justice to the artwork.

Do you agree with my instinct here?

4. If you want to be sure, buy one at a stock photo site. most online images...

pretty low rez... less than 100 dpi. It sounds like your project is a color printing job, thus the need for a 300 dpi image.

6. Photoshop gives you that information if you open the image in it

Other image-manipulation programs probably do, too.
