The foot valve in a well should be the same size as the down pipe, usually 1 inch, but could be as small as 3/4 or as large as 1 1/2 . Foot valves are made in all those sizes.
A foot valve is something that you eat with your foot
Are you sure you don't mean 'foot valve' - this is the valve at the bottom of a well suction pipe when you use a jetpump. I've never heard of 'foot trap'.
That is like saying what size is an automobile. Which size valve?
To test a foot valve in a shallow well, first ensure the pump is turned off. Remove the foot valve from the well and inspect it for any debris or damage. Submerge it in a bucket of water and manually operate the valve to see if it holds water and creates suction. If it fails to hold water, it may need cleaning or replacement.
A foot valve is not required in reciprocating pumps because these pumps can create suction and effectively draw fluid into the pump chamber during their intake stroke. Unlike centrifugal pumps, which rely on continuous flow and need a foot valve to maintain prime, reciprocating pumps can handle intermittent flow and are designed to operate with a positive pressure during the suction phase. Additionally, the check valves within the pump ensure that fluid flows in the desired direction and prevents backflow, eliminating the need for an external foot valve.
The same size as the pipe it is hooked up to in the well.

It will only work properly if you put it very close to the foot valve. In which case you may as well replace the foot valve - it's not difficult to do. If you put it at or near the pump, the pump will just suck air.

his foot size is 8
Miranda's foot size is probably 7
1 foot size is 12 inches
DN 50 means: "DN": Diametre nominel - Nominal diameter of the valve, and "50" is the size of the valve in [mm]. Alternative is NPS (Nominal pipe size in inches).
