Depth of field table
Distances are measured from the sensor plane. Each cell shows the near and far limit of acceptable sharpness in metres (∞ = to infinity). Circle of confusion = sensor diagonal / 1500.

FAQ
What is the depth of field of the Canon EF-S 10-18mm F4.5-5.6 IS STM at f/5.1 and 3 m?
At 14mm, f/5.1 and focus at 3 m, everything from 1.22 m to infinity is acceptably sharp.
What is the hyperfocal distance of the Canon EF-S 10-18mm F4.5-5.6 IS STM?
At 14mm and f/8 on a APS-C sensor the hyperfocal distance is about 1.32 m. Focus there and everything from 0.66 m to infinity is sharp.
How do I get more background blur with the Canon EF-S 10-18mm F4.5-5.6 IS STM?
Open the aperture to f/5.1, move closer to your subject and increase the distance between subject and background, and zoom in to the long end. You can check the result in the calculator above.
