L Shape Concrete Calculator

This L shape concrete calculator splits an L-shaped pour into its two rectangles, sums their areas, and applies one thickness — wraparound patios, garage extensions and L-shaped house slabs in a single calculation.

इस कैलकुलेटर का उपयोग कैसे करें

  1. अपने आयाम दर्ज करें — लंबाई के लिए फीट, मोटाई के लिए इंच.
  2. विकल्प समायोजित करें — अपव्यय प्रतिशत, बैग का आकार और आपके स्थानीय कंक्रीट की कीमत।
  3. अपने परिणाम पढ़ें — टाइप करते ही आयतन, बैग, वजन और लागत लाइव अपडेट होते हैं।

सूत्र

L-shape volume = (L₁ × W₁ + L₂ × W₂) × thickness

हल किया गया उदाहरण: A patio 20 × 10 ft with a 10 × 8 ft leg, 4 in thick: (200 + 80) × 0.333 = 93.3 ft³ ≈ 3.46 yd³.

Every l-shaped concrete calculator works the same way: decompose the L into two rectangles. Measure the full outer rectangle of one leg, then the remaining leg — don't double-count the corner where they meet.

The easiest split: extend one leg to its full outside length, then measure the second rectangle only up to where it meets the first. Sketch it before you measure; five minutes with a pencil prevents a half-yard mistake.

U-shapes and T-shapes decompose the same way into three rectangles — run the third section through the irregular shape calculator, or add two L-calculations.

अक्सर पूछे जाने वाले प्रश्न

l shape concrete calculator के बारे में सामान्य प्रश्न।

How do I measure an L-shaped slab?

Split it into two rectangles at the inside corner. Measure one leg at full outer size, the second only to where it meets the first — never overlap them.

Both legs different thicknesses?

Rare, but possible: run each leg separately through the rectangle calculator at its own thickness and add the results.

What about T- or U-shaped slabs?

Same principle with three rectangles. Use the irregular shape calculator, which accepts multiple sections.

How much waste for an L-shape?

5–10%. The inside corner is a natural crack point — plan a control joint at the re-entrant corner regardless of waste.
