But, as I understand it:
   1/4 acre, typical for suburbs;

 An acre is 208.7^2 feet.
My 2450 sq-ft house sits on 95×65 foot lot; 14% of acre.
With 5 foot easements on all sides.
 

Realizes I can check distances using Google Earth (in meters)...
Distance: Closest neighbors are across the street, at roughly 45 meters (148 feet).
Next closest neighbors: 65 meters (214 feet), and 63 meters.
Neighbor with bigger yard, roughly 100 meters (330 feet).
Their yard is approximately 150 x 75 meters (495 x 248 feet), so, around 122760 ft^2, or around 3 acre.
My yard, ~ 50 x 45 meters,  165 x 149, so ~ 24585 ft^2, or around 0.6 acre...
So, my yard isn't all that big though it seems...
Actually one of the smaller ones on the block, apart from one house on the corner (~ 45 x 45 meters).
Block size is roughly 200 x 400 meters.
   With, the 400 meter stretch of road having 7 houses.
So, around 57 meter average house-to-house distance. The 200 meter sections have 3 houses on each side, so around 67 meter.
The houses near the middle of the block tend to have bigger yards.
But, 16 houses on the block, statistical average yard size on this block: 49500 ft^2.
Finding relative's house on map, yard is around 30 x 75 meters, 99 x 248 feet, 24552 ft^2.
Horse area is around 60 x 245 meters (200 x 808 feet, or ~ 161600 ft^2, ~ 3.71 acre).
There are some nearby undeveloped areas: 600 x 400 meters, and 800 x 800 meters.
Distance from my house to central part of Tulsa: ~ 11 km.
Distance from my house until reaching undeveloped areas: ~ 4km.
Also not that far from the airport, which is actually rather large (around 3km x 4km). With around a 3km stretch of runway.
The center part of the city is seemingly mostly crammed into a 2km x 2km square.

     Much of the lot is taken up by the house itself.
     Yard is mostly superficial (*1).
   1/2 acre, slightly bigger yard
     Say, neighbor's house is like 20 feet away or something.
   1 acre
     Roughly the size of a typical used car lot or gas station.
   2 acre
     Roughly twice the area of a gas station.
     Could fit multiple houses if each had a smaller yard.
