Having a pixel count of 1773 x 1183 this file should produce:
A high resolution 15 x 10 cm (6 x 4 inch) picture for professional quality printing at 300 dpi
A medium resolution 22.5 x 15 cm (9 x 6 inch) picture for good home printing at 200 dpi
A low resolution 45 x 30 cm (18 x 12 inch) canvas at 100 dpi.
FULL SIZE IMAGE
The exact size of every full size image is shown towards the bottom of the descriptive text.
The quoted dimensions refer to printing at 300 dpi (dots per inch) which will produce a high resolution picture for professional use.
For good home printing it would be perfectly acceptable to multiply those dimensions by 1.5.
For a canvas print where fine detail is not essential, the dimensions could be multiplied up to three times.
