make it in 5000 x 4000 pixels dimension with resolution between 400 and 500. This will help it to look clean and professional while printing. The image size will come around 30 mb. If your computer has a good processor speed (more than 5 ghz). You can change the canvas size to the original size you want (500 x 400 cms) and can use lesser image dimensions with res 300 to 500, but the image weight will go in gbs. around 10 gb may be.

you can create a new document in photoshop with 5m X 4m. After you have juste to slide and stretch your photo in the new document.
You can make it 50cmx40cm but make sure you have the option of large file type selected when saving. To achieve maximum resolution, However, it will all depend on the printer capabilities to get accurate coloring and resolution.

5 Meters by 4 Meters is pretty big, and you may want to send it to a professional printing place like AlphaGraphics to get the best output.
You should always make your poster a lot bigger then what the actual print is going to be.
