72 PPI Web Resolution Is A Myth

Did you know that only the number of pixels in an image, not the pixel per inch (ppi) setting, determines what an image looks like when viewing it on a monitor, how large the file is and what quality it is? Yep. In this video I explain why the ppi resolution does not matter, despite what we all learned.

I've watched so many videos and read so many books on the subject of resolution and print size and image resizing and i must say this is the most informative video I've watched. Finally got it. Liked, subscribed.

This is the clearest explanation I have ever seen on this subject and that includes my college print production class. THANK YOU!!!!

[StephenDesRoches]

I would thumbs up this video a hundred times if I could. So much confusion exists on this topic.

[rolfmeier]

Your explanation really makes sense. It's perfect how you explain the context and the relationship of the different parameters.

[flowerlilyevents]

OMG thank you for explaining this so clearly!!! I was feeling so overwhelmed and confused before I saw this video- thank you, thank you, thank This is the best explanation ever :D

[GRJ]

Sean. This is the best explanation on this matter I've ever seen. Thanks and congrats

[katielake]

I'm so glad I just found this video! You saved me hours of time resizing all my website images because I thought changing them up to 72ppi would improve the load speed. So informative! Thank you

[SouthernOregonCoast]

Great explanation Sean.
I like to think of those pesky picture elements as dots on a balloon and visualize them just getting separated more or less with the volume of air.

Hello Sean,
Thank you for this great tutorial. You are bookmarked, liked, subscribed, and watched at least 5 times since I found you only a week ago. You are my digital hero. Thank you so much.

[mohammadmoaid]

finally, a clear and professional explanation on this confusing topic, well stated!

[SveinWisnaes]

Thank you for making this video! I have been "preaching" this for years in my classes, and it still surprises people. And some of them need to actually test it themselves when I tell them that changing PPI does not change the file size :-D

*Sean Bagshaw* Your video helped me a lot to clarify this topic. *But after the first impression, the following details and facts confused me:*
1. If PPI is Pixels *for the screen* and DPI for the Printer, then why Imaging apps are using the "PPI" for Printing (instead of DPI)? See minute 1:41
2. When i scan my 35mm negatives at 300 DPI the image is a small file. When i scan them at 4800 DPI, the image is huge as a file and as a
number of pixels. I use Epson V350 Photo, with Auto Film Loader.
3. I printed a poster twice, at the same lab. The first time the photographer, printed it at 300 DPI and the second time at 200 DPI (both times in
the front of my eyes. Not only do both posters have exactly the same size 70x100cm, but the 300 DPI poster had a better quality.
4. Another time, in another lab, the photographer printed a high-quality photo (as a poster) at a lower DPI (not at 300 as i first thought).
I told that to a photography teacher and he said this was wrong and that he should print it at 300 DPI.
5. Years ago, i remember a Canon Printer that allowed me to change the size of the image on the paper (on-screen), as i do with Windows on
my desktop. And this, just a step before clicking on Print, i.e. the DPI settings haven't changed.
So, what is going on here?

[MrPhillipgraham]

I get it!! This makes total sense, I now understand image sizes compared to my monitor resolution, thanks so much! I had no idea PPI didn't matter for sharing images online.

[pauljenkin]

Having played with the resample option in PS, I've always sort o known this but your explanation was very clear and understandable for a non-tecchy person such as myself. Thank you.

[ldouglass]

Try as I might, this goes right over my head. I wish I could grasp it. All I want to know is settings to use for posting on my website and best settings I need to use for printing to my printer. I'll keep searching for PPI resolution for dummies. Thanks for trying

[trevornorris]

the easiest and clearest to follow I've seen to date

[chrissveenphotography]

Thanks for clearing this up! It makes sense now. I REALLY love the sharpen for web feature in TK actions. Would love to see an instruction video on full resolution sharpening please!

[NecroNicki]

Thank you for explaining this so clearly! 😊

[senthilkr]

Fantastic. I have been saying this for long time, but never agreed. Hereafter, I am not going to bother anymore whether they agree or not. Thank you for the video.

I like your exploration of this topic as well. I have long wondered about this ever since the 90's. Sometimes saving an image from the net resulted in a high quality pic, sometimes it didnt. Even photoshop cant fix some images. For example, if an image is physically too small, no matter how many ppi/dpi you set, if you enlarge the said image, it will have bad results. But most of this comes from an older age of the internet. A time when there were very few photo manipulation software options. Before the trendy, super user friendly website development tools that we have today. Before the modern digital cameras. Back then, general consumers only had webcams and pocket cams that might have produced a 4 mega pixel image. This was also when film cameras still reigned king. We would use scanners for everything. Telephonic fax modems. Hahaha. People just dont know how easy they have it now. Great video.
