Newbie to printing and sizing

Bear with me on this subject but it is totally new to me.
I use Arcsoft panaroma maker 4 which is quite easy to use.. however when i go to printing the end result is that the paer size is 20" X 8" but the actual picture is only 18" x 3.75 ".
Is there any way that i can increase the size of the picture to say 18" x 7".
I do take the photos in portrait mode.Are there any specialist firms that will cater for this in the UK or is there anothere easy way.
I am willing to listen to any basic suggestions.
Cheers

The aspect ratio of the print is defined by your 18" x 3.75" image file so to print it at 8" height the length would need to be increased to 38.4" (i.e 18" x 8"/3.75") if you wished to retain the aspect ratio. You could change the aspect ratio in Photoshop or similar by unlinking the the height/width and just resize the height but this would result in a vertically stretched image which may, or may not, look odd.
An alternative would be to create a blank image file that was 20" x 8" and copy into it your image plus another image of similar proportions and print two images together which would at least save paper. I've recently done this with three 36" wide panoramas which I had printed on a 36" x 24" sheet and then separated them for framing (much cheaper than 3 separate prints) as shown below (if it displays anything)

If you increase the height of the image in Photoshop without maintaining the aspec ratio, the image will be stretched vertically not unike a short person in a house mirrors that makes them look 10 ft/3m tall.
What it sounds like you need is more vertical field of view from the camera you used. If you turn the camera sideways (portrait position) and shoot the same scene again, you'll need a few more shots to get the same view you have now, side-to-side, but will have a taller FOV for the photo that will make the image taller.
With the software you're using thats about all you can do

ignore the custom pixel ratio. Just goto Image size, uncheck constrain Proportions, change the resolution if needed; for printing I would suggest you use a minimum of 150 pixels/inch, preferably use 300ppi. Then in the Document size change the units to inches and enter the print size you want. At the bottom select Bicubic smoother as you are enlarging the image. Then hit ok.
View the image at 50% magnification and apply the smart sharpen filter I use it set at 100%, 0.2, 0 and apply it a number of times until the image looks just too sharp at 50% then undo one or two steps of sharpening.

Excellent thank you for that, it worked a treat, but i will have to send it to Photobox to be printed.
Just one point, the scene is a panaromic mountain scene, but on my screen the mountain tops look a bit out of shape.. is this is a case of screen size or is it one of them things that happen ?
Many thanks

Can you post a small version online for us to look at? The distortion maybe a function of the stitching which could be corrected. The forum experts should be able to help with that as I'm primarly a photographer and I really am a newb when it comes to panoramic work. Photobox are a very good print house I get a lot of my work printed there.

Thanks for your help i have learnt a lot !
I have increased the size of the image to 30 " and the mountain peaks have levelled themselves out to what they should be !, so it is to do with the size of the print that you require.
Cheers
