I break down diameter and weight ratings to stop ice heave. This guide helps you pick the right pool safety cover for your specific pool size.

Jonah wouldn't reorder this if… Match the cover diameter to your pool opening to ensure a tight seal against debris. Verify the weight rating is high enough to prevent ice heave during winter months.

The chore here is keeping water out and ice pressure off your liner. If the cover is too light or the diameter is off, you are fighting freeze damage all season.

Before you open the listing, look at the product photo to confirm the stated diameter matches your pool. Check the weight rating in the title to ensure it is heavy enough to stay sealed.
