Choosing the correct tarp size is essential for equipment safety, weather protection, and long-term cost savings. We recommend measuring equipment dimensions precisely, adding appropriate overhang, accounting for tie-down points, and selecting a tarp material suited to environmental exposure. Oversized tarps improve coverage, while undersized tarps increase the risk of damage, corrosion, and UV degradation.
Selecting the right tarp size is not a cosmetic decision. It directly impacts equipment lifespan, operational readiness, and safety compliance. A tarp that is too small exposes critical components to rain, snow, UV radiation, wind-driven debris, and condensation, while a tarp that is excessively oversized can lead to wind lift, pooling water, and premature fabric stress.
We approach tarp sizing as a risk management process, not just a measurement exercise. Proper sizing ensures:
-
Full surface coverage, including vulnerable edges
-
Secure anchoring without excessive tension
-
Adequate airflow to reduce moisture buildup
-
Long-term durability under real-world conditions
How to Measure Equipment Correctly Before Choosing a Tarp
Step 1: Measure Length, Width, and Height
We begin by measuring the maximum dimensions of the equipment:
-
Length: End to end, including protrusions
-
Width: Widest point, accounting for attachments
-
Height: From ground level to the highest component
Measurements should always be taken in feet, rounding up to the nearest inch for accuracy.
Step 2: Add Overhang for Full Coverage
We recommend adding at least 12–24 inches of overhang per side to ensure:
-
Protection from wind-driven rain
-
Coverage of tie-down points
-
Reduced edge exposure to UV rays

Choosing Tarp Size Based on Coverage Style
Top-Only Coverage
Used when equipment is already elevated or stored indoors.
-
Add 12–18 inches per side
-
Focus on UV and dust protection
Full Drop Coverage
Ideal for outdoor storage and winter protection.
-
Add 2–4 feet per side
-
Allows secure ground anchoring
-
Reduces splash-back and snow intrusion
Wrapped or Enclosed Coverage
Used for long-term storage or transport.
-
Oversize by 30–40%
-
Requires reinforced grommets and breathable materials
Material Choice Impacts Effective Tarp Sizing
The material type directly affects how a tarp performs once installed.
Poly Tarps
-
Lightweight and waterproof
-
Minimal stretch
-
Best for short- to medium-term coverage
-
Size accurately; limited flexibility
Vinyl Tarps
-
Heavy-duty and industrial-grade
-
Resistant to tearing and abrasion
-
Slight rigidity requires extra overhang
Canvas Tarps
-
Breathable and condensation-resistant
-
Ideal for machinery with metal components
-
Natural shrinkage requires upsizing by 1–2 feet
Environmental Factors That Influence Tarp Size Selection
We factor in real-world conditions, not ideal storage scenarios.
Wind Exposure
-
High-wind areas require larger tarps for secure anchoring
-
Additional grommets and weighted edges improve stability
Snow and Rain
-
Oversized tarps prevent runoff from reaching the equipment base
-
Steeper drape reduces water pooling
UV Intensity
-
Southern and high-altitude regions demand full surface coverage
-
Extended overhang protects seams and edges from degradation
Common Tarp Sizing Mistakes to Avoid
-
Choosing tarp size based only on flat dimensions
-
Ignoring height and protruding components
-
Failing to account for tie-down clearance
-
Using exact-fit tarps with no overhang
-
Undersizing in high-wind or winter conditions
Each of these mistakes increases equipment wear, corrosion risk, and replacement costs.
Best Practices for Safe and Secure Tarp Installation
We recommend:
-
Centering the tarp evenly before securing
-
Anchoring from the middle outward
-
Using bungee cords for flexibility, not rigid rope
-
Ensuring airflow at ground level to reduce condensation
Proper installation complements correct sizing and maximizes protection.
FAQ: Equipment Tarp Sizing
What size tarp should I use for equipment storage?
Choose a tarp that exceeds equipment dimensions by at least 2–4 feet on each side.
Is it better to oversize or undersize a tarp?
Oversizing is always safer and provides better protection and anchoring options.
Does tarp size include grommets?
Yes, tarp sizes are measured from edge to edge, including grommets.
How much overhang is recommended for outdoor equipment?
We recommend a minimum of 24 inches per side for outdoor storage.
Do different tarp materials affect sizing?
Yes, canvas and vinyl tarps often require additional sizing to account for stiffness or shrinkage.
Final Thoughts: Choosing the Right Tarp Size with Confidence
Selecting the correct tarp size is a strategic decision that protects valuable equipment, minimizes maintenance costs, and ensures year-round operational readiness. By measuring accurately, accounting for environmental exposure, and choosing appropriate overhang, we ensure maximum protection with minimal risk.
A properly sized tarp is not an expense—it is an investment in equipment longevity and safety.
