Lightroom Ecosystem: Ability to create a Custom Crop Ratio preset

with all of this cloud stuff, we should be able to define a list of custom aspect ratios and have them available across all instances of lightroom; whether it be at home in front of the PC, on my phone or ipad. or even browser based from a different computer. Its a bit ridiculous that this hasnt been fixed at this point. 

What an absurd oversight on the part of Adobe! This is so frustrating and may prove to be too much of a problem for me in my print work flow to continue using CC. 

6x7 is an absolutely classic aspect ratio in photography used by many professional cameras.
Not for Adobe though.
Please bring back the custom ratio, or at least add the 6x7 option.
Your paying customers will thank you it.

I've never even used lightroom classic but as an amateur photographer I'm finding there are a heap of features missing in Lightroom CC, It's really frustrating. Why are basic features not added? Who decides the reason the features aren't worthy enough to give your customers who have been begging for years. 

This reply was created from a merged topic originally titled How do you enter a custom crop ratio like 21:9, 18:9?.

I am trying to crop a extra wide wall paper out of a photo. The widest option is 16:9 while I need 18:9 and 21:9. I know there is a custom option, but it is really hard to determine whether your custom crop is really 21:9 or 18:9, you kind of just have to guess. Is there a way to enter those specific crop dimension?

Adding to this thread—this seems like a necessary UX feature to reduce the clunkiness juggling between Adobe products for a simple crop.

I am just going to pile on here because this is absolutely ridiculous. They have two separate lightroom products to do similar things, but they removed one of the most basic and important features to every user. I spent the entire day editing in CC only to come to find that I cant set a custom crop ratio for instagram. The custom crop they have here is a joke, no measurements, no rulers, you might as well just be guessing the size at that point. Useless. Now I have to install classic so i can crop to the correct ratio, or go to photoshop. I thought lightroom was created to get classic photo editing features OUT OF photoshop, and more accessible to everyone else.

Agreed - i need custom crops...i use 3:1 and 2:1 a lot....as it is its like guessing!

it ́s an old problem, and it ́s stranges, that Adobe never reply. 

Just spent ages trying to work out how to crop 1:2 - now realise I can't.  Absolutely gutted ....

They definitely need to add this feature. Absurd that Ligthroom CC is so watered down and also they only way to smoothly work between a mobile and desktop workflow. 

11x14 is a standard ordering size and I have to recreate that as a custom size EVERY SINGLE TIME, please allow a permanent save!

Just chiming in here as a new CC user.  This seems like an extremely simple addition to the software to make it more user friendly across a wider range of photographer's styles.  

Hello?!?!  Adobe can you hear us?  Please add user inputted aspect ratios.

Adobe, 
Please add this feature, I've just gone to crop some medium format style photos, and I can't crop to 6x7... It's such a basic feature! I can't believe that has skipped 2 years worth of sprints and backlog refinements... feels kinda like you're avoiding putting this feature in to force people to use LR Classic.
Please listen to your users! 

This is a very basic and useful function that's necessary for printing photos. Please reintroduce it.
