I have been working on some renderings and when they are complete, I export them and open them up in photoshop. The quality of these renderings is not very good. I set the quality to 'best' and have played around with setting the resolution to both 'screen' and 'printer', but nothing seems to change. What do I need to do to increase the size and DPI of my renderings so I can blow them up on larger 24x36 sheets?? I am using revit 2012 at work and 13 at home.
Thanks!

What size view did you use? You can't expect to blow up a small view.

I have it set at best. Do I need to change the scale of the perspective drawing?

The size of the rendering is based on the views extents that you are trying to export.
Ex: start a blank project, draw a single wall and in the render dialog, look at the image size. Then draw a much longer wall and you will see that the image size increases automatically...zoom factor does not matter for rendeging, hence the ability to render a region in the render dialog.
To get around this, save the rendering to your project and and then export that saved view out as an image and in that dialog you can scale it accordingly.
Alternatively, you can rescale the image in photoshop ... i strongly encourage reading up on this first as there are propper techniques to follow in doing so.
NOTE: Saving renderings in a project environment will greatly impact your project in file size. Always keep that in mind.

I said size - not scale.

Thanks! That seemed to work by saving the image to the file and scaling it higher when i export it. I have been trying to figure this out for a couple months now

How much file size would the project be impacted if a rendering was included in the project? Is there a general rule of thumb for this? i.e. a 4 x 6 rendering on best at screen resolution takes up X amount of Mb's?

We never save a rendering within the file because there is no need to. We always export the image to a file, then if we want a rendered view on a sheet, we insert a jpg image with an appropriate resolution.

What if the client has an agreement that requires the images to be "embedded" in the model and you can't convince them that's a bad idea? haha!

I usualy set the Size Crop to the paper size, if I'm gonna print in an A4 paper, I set the Size Crop to be 210x297mm and adjust the resolution in the Render dialog, for 150dpi most of the times. It turns out to be very good when printing. I think there is no point rendering an image too large if the print size will be small.

It sounds to me like a size crop issue. Clich the view extent box and scale it to be about half the size it will be printed at. THEN render at your chosen quality. It takes longer to render but delivers a quality image at the size ou need.
Or go full scale. I rendered a 40 inch image last month
