I suspect ordering a slightly oversized liner will make wrinkle removal a bit harder, but in many installation videos, I see the liner needs to stretch to fit the pool.
Additionally, when the pool is partially drained for the winter, sometimes the liner peels from the corners. I probably drained a bit too far, hence my liner replacement.
I was thinking of adding an inch or two to X and Y measurements. I suspect these measurements are within the tolerance of most people's ability to measure accurately, including my own.
Does this sound like a reasonable idea?
