Multiply your area's length by its width to get the square footage. Then divide by the roll coverage to get the number of rolls needed. Add 10–15% for overlaps and edges. The DOTDAY Fabric Calculator does this automatically - just enter your dimensions and select your ground condition.

Choose based on your application. Use SHIELD 3.2oz for garden beds, farm rows, and under mulch - it's lightweight and breathable. Use XBAR 5oz for gravel driveways, pathways, and hardscape - it's dual-layer and load-bearing. Use TERRA 4, 6, or 8oz for drainage, French drains, and retaining walls - it's engineered for water filtration. The calculator recommends the right weight automatically.

It depends on your roll size and area. A 3ft x 100ft roll covers 300 sq ft. A 4ft x 300ft roll covers 1,200 sq ft. Enter your dimensions into the DOTDAY Fabric Calculator above and it will tell you exactly how many rolls to order - including overlap allowance.

Overlap fabric strips by at least 6 inches to prevent weeds from pushing through the seams. For high-weed-pressure areas like garden beds, use 8–12 inch overlaps. The DOTDAY calculator adds a 10% buffer to your total roll count to account for overlaps automatically.

Use XBAR 5oz dual-layer woven fabric under gravel, decorative rock, and paver driveways. It's engineered to handle the weight and pressure of hardscape without shifting or collapsing. Standard 3.2 oz fabrics are not recommended under gravel as they can break down under load.

No - different applications need different fabric weights. SHIELD 3.2oz works well for garden beds and planted areas but will break down under gravel. XBAR 5oz is built for hardscape and high-traffic ground. Use the DOTDAY Fabric Calculator to match the right fabric to each zone in your project.

Break your area into simple rectangles. Measure the length and width of each rectangle separately, calculate the square footage of each, then add them together. Use the DOTDAY Fabric Calculator for each section individually and total up the rolls at the end. Always add 10% for overlaps and waste.

Geotextile fabric is a non-woven permeable fabric engineered for drainage, filtration, and soil separation - not primarily for weed control. DOTDAY TERRA is a geotextile fabric available in 4oz, 6oz, and 8oz weights. Use it for French drains, retaining walls, road base, and erosion control where water management is the priority.

For 1,000 sq ft, you need approximately 1,100–1,150 sq ft of fabric after adding 10–15% for overlaps. That works out to roughly 4 rolls of SHIELD 4ft x 300ft (1,200 sq ft total) or 11 rolls of XBAR 3ft x 100ft (1,100 sq ft total). Use the DOTDAY Fabric Calculator above for an exact roll count based on your specific roll size.

Yes. All DOTDAY fabrics are permeable - water, air, and nutrients pass through to the soil below. SHIELD 3.2oz and XBAR 5oz allow moderate water flow ideal for planted areas and hardscape. TERRA non-woven geotextile has high permeability specifically designed for drainage and water filtration applications.

DOTDAY fabrics are UV-stabilized and designed for long-term outdoor use. SHIELD 3.2oz lasts 5–10 years under mulch. XBAR 5oz is rated for 10+ years under gravel and hardscape. TERRA geotextile fabrics are engineered for permanent installation and often lasts upto 50+ years under ideal conditions for drainage and infrastructure applications. Covering with mulch or gravel significantly extends the lifespan of any fabric.

Yes. All DOTDAY landscape fabrics are chemically inert and safe for use around edible plants, vegetables, herbs, and food crops. They help retain soil moisture, regulate temperature, and reduce the need for herbicides - making them a preferred choice for organic growers and commercial farms using SHIELD 3.2oz in their growing rows.
