Hello everyone,

I have a problem with print sizes.

I would like to printa 20x30cm format on a A4 sheet but i aways end up with a width of 20,5cm.

I have an Epson P900, i must be missing something...

I just tried again, I cropped my image to 20x29.7 but it still comes out at 20.5x29.7

These are not the right numbers to use when cropping. They don't match the numbers I stated twice.

My apologies but I want to make a 20x29.7 and not 21x29.7

First of all, a big thank you for your feedback, it’s very kind!

I'm a professional photographer and I also sell frames, that's why I need to crop my photos. 

Here are screenshots of my settings (sorry it's in French...).

And despite my request to print in 20X27cm, I always have 20.5cm more or less.

That's 21.0x29.7

If you don't crop this photo to exactly the aspect ratio 210x297 (or 21.0x29.7) before you print on A4 paper, you can get strange things like 20.5cm. Are you cropping to this aspect ratio? (I can't see your screen captures, I can't see anyone's screen captures, you need to include screen captures by clicking on the "Insert Photos" icon)

In addition to what dj_paige said (the image aspect ratio must match A4 for even margins)…

Which A4 paper size is selected in the macOS Page Setup dialog box?

The size you pick determines:

The available print area
Whether the print will be scaled

If we know what the selected paper size is, that might provide a clue for what’s happening.

(My screen shot is for an older Epson photo inkjet that’s similar to the P900)

Also, in the Format For menu, make sure that the P900 is selected. If it’s set to Any Printer, you’ll get a generic list of paper sizes that might not match the capabilities of the P900.

Before you print you have to crop the image so that it is A4 aspect ratio, which is 297x210 (or 210x297). You cannot print 20x30 on an A4 sheet because it doesn't fit — unless you expand or shrink the image in one direction (and you'd have to use Photoshop to do that and you wouldn't like the way it looks) or you deliberately set up the print so that there is a certain amount of white space on the printed image or the printer crops the image.
