bkyser Loc: Fly over country in Indiana

I'm doing 16 photos for a museum, and they want them in existing matted frames. The opening is 19x28.

Right now the photos aren't cropped, so they are all 2x3 ratio.

What ratio is 19x28, so I can crop in lightroom and get a good feel for the best parts to "cut out" when cropped?

Told you, I'm math challenged.
If anyone's interested in seeing the photos they chose from, you can see them under "edited car photos" at

Lucky you, its almost 2:3 ratio as is. (19x28.5 would be 2:3)
Just print 20x30 and mount them, adjust position as needed and you will be fine. Or print at 20x30 with 1/2" border for a closer fit and less lost image.

The ratio of 19" x 28" is 19:28. 18.6666" X 28" would be a 2:3 ratio, or 19" X 28.5" would be more to the point since you want to fill the opening.

Therefore, you need to crop one half inch from the long side of your images, or 1/4" from each end if the height is 19".

19" x 28" is very close to 20" by 30" which is, of course, 2:3.

Thanks MT and Mike. It sure would have been nice if the mat was 19x28.5, seems that would make sense, but at least I know I can adjust it and not lose much. I'm a people photographer, but keep getting hired to do things like this. I can't complain, but I have the hardest time getting good expressions out of cars or cityscapes...

I'll get cracking on cropping these tonight and hopefully get to take advantage of some cyber week printing deals on top of it.

Appreciate those that paid attention in math class.

Good luck with the project.

The site wouldn't let me in to see your photos without giving my email address. I already get too much spam so I am reluctant to give the address out. Is there any other way to see your images?

That info only goes to me, I don't advertise so you wouldn't get spam from me, but I completely understand.

It's supposedly a way to build my mailing list, but whenever I delete the gallery, I just delete the email addresses. Fortunately, I stay busy enough without bugging people.

Old-time tool for answering these questions as they come up: a slide rule. I always kept one in the darkroom, and now keep one within reach of the dry, bright desk when I'm doing post processing and printing.

The benefit is that when you set a number on the C scale next to a number on the D scale, all the other numbers on the C & D scales are the same ratio to each other. (There are no decimal points on these scales, so 2 over 3 is the same as 20 over 30, etc.) While you don't have the third-decimal-place precision you get with a calculator, you CAN SEE and scan ALL the ratios AT ONCE.

While there are collectible slide rules that fetch high prices, ones that would be suitable for print sizing purposes are available beginning at a few bucks on ebay and probably elsewhere. I prefer the Pickett aluminum models with black numbers on yellow, just for ease of reading, but that's a personal choice. And if you can find an affordable CIRCULAR one ("Concise" brand is one I bought new within the last 10 years, but I can't find a listing for one at the moment) you never end up with the slide sticking way out of the tool.

Wish I had my old Pickett back - loaned it to a cute girl in grad school and never saw it again 😹.

19/28 is equivalent to 2.036/3 so you won't have to crop but a very tiny bit (0.036) off the 2.0 side.

Thanks.

The images look great.

To put in another, hopefully more simple way, 19 / 28 = 0.678... close enough to 2/3, which is 0.6666666... .
Or, 28 / 19 = 1.4736... close enough to 3/2, which is 1.50.

Good answers to your question; I wanted to share an app I have on my iPhone (also available for Android). It's called "Logan Border Calculator" and it does all the math for you for any size.

When I know that I will have to crop a shot, I leave enough room around the edges. Math doesn't enter into it. The last thing I want to do when I'm out enjoying myself shooting is to start working on math problems. From the detailed numerical answers you got, you can understand my thinking. I like the idea of an app, though.

Thanks. I just installed it.
