Check Latest Price on AmazonWhich One Should You Choose?
If budget is tight → choose the 12' x 16' 2-Pack (ASIN B07FTX4V6K) for value and multiple covers. If you need portable seasonal protection → choose one of the 10 mil options (ASIN B07GZWRQLJ) for a balance of durability and weight. If premium, long-term protection matters → choose the 20 mil 16' x 20' (ASIN B077Q4YRD3) for the best heavy‑duty value. For very large coverage where weight is less of a concern, the Top Rated 30' x 60' (ASIN B07JJZS3B2) is the easiest to drape over big patio sets.
Best for Specific Scenarios
- Protecting patio furniture: 30' x 60' (B07JJZS3B2) because its large coverage drapes over multiple chairs and tables with room for tie-downs.
- Temporary roof or canopy repair: 16' x 20' 20 Mil (B077Q4YRD3) because the thicker material resists tearing when fastened under tension.
- Small covers & multiple items: 12' x 16' 2-Pack (B07FTX4V6K) because two tarps let you cover separate pieces or create layered protection affordably.
Frequently Asked Questions
How thick should a tarp be for patio furniture during spring storms?
For short-term storm protection a 5–10 mil tarp is usually adequate; 10 mil offers a good balance of protection and handling. If you expect long-term exposure or heavy wind, choose 20 mil for better tear resistance.
How do I prevent a tarp from ripping in wind?
Use the rope‑reinforced hem and rust‑proof grommets to tie the tarp down evenly. Avoid sharp contact points under the tarp, add padding over edges, and anchor multiple points to spread tension. Using bungee cords or ratchet straps with padding reduces stress on grommets.
Can I leave a tarp on furniture all season?
You can, but choose a UV-resistant tarp and check periodically for trapped moisture or mildew. For year‑round covers a thicker, 20 mil tarp is better; lift and air out items occasionally to avoid mold and material breakdown.
