Notes for a 16 × 40 driveway
- 16 ft lets two small cars sit side by side in a pinch, but doors will be tight; 20 ft is the usual two-car minimum.
- At 640 sq ft, the job size is close to the national average driveway that cost guides use, so published averages fit this size reasonably well.
- A wider driveway is usually laid in two paver passes, which leaves a joint down the middle. Ask how the crew will seal that joint.
