🎨 Paint Calculator Tool

Estimate your paint needs accurately and effortlessly.

The Formula We Use

To provide an accurate estimate, our calculator uses a standard industry formula:

1. Calculate Total Surface Area:

Total Area = (Total Wall Width × Wall Height)

2. Subtract Non-Paintable Areas:

Paintable Area = Total Area - (Number of Doors × 20 sq ft) - (Number of Windows × 15 sq ft)

3. Determine Total Paint Needed:

Gallons Needed = (Paintable Area / 350 sq ft per gallon) × Number of Coats

Note: We assume a standard door is 20 sq. ft., a standard window is 15 sq. ft., and one gallon of paint covers approximately 350 sq. ft. The final result is rounded up to the nearest whole number.

5. Frequently Asked Questions (FAQs)

1. How accurate is this calculator?
This calculator provides a very close estimate for standard rectangular rooms. It’s based on industry averages for paint coverage and standard sizes for doors and windows. For best results, always measure your walls carefully.
2. What if my room is not a simple rectangle?
For L-shaped rooms or rooms with unusual layouts, the best approach is to measure the total length of every wall you plan to paint and add them together. Enter this combined length into the “Total Wall Width” field.
3. Does this calculator account for ceilings or trim?
This calculator is specifically designed for walls. Ceilings and trim should be calculated separately. To calculate a ceiling, you can treat it as a single “wall” by entering its length and width into the calculator (and setting doors/windows to zero).
4. What is the standard paint coverage you use?
We use a standard estimate of 350 square feet per gallon of paint, which is a common average for most interior latex paints on a smooth surface. Coverage can vary based on the paint’s brand, type, and the texture of your walls. Check the paint can for the most accurate coverage information.
5. Why is it recommended to buy slightly more paint than the estimate?
It’s always a good idea to have extra paint on hand for future touch-ups or in case of accidental spills. The estimate is precise, but factors like wall porosity and application technique can slightly increase paint consumption. Having a little extra from the same batch ensures a perfect color match later on.

Frequently Asked Questions

1. What concrete grade should I use?

It depends on the application. M15 is suitable for light-duty pavements and non-structural work. M20 is a common standard for residential slabs and foundations. M25 is used for reinforced concrete columns and other high-strength requirements. When in doubt, consult a local building professional.

2. Why is a waste factor necessary?

A waste factor accounts for real-world conditions. Spillage, over-excavation, an uneven subgrade, and formwork deflection can all lead to using slightly more concrete than theoretically calculated. A 5-10% waste factor is a standard industry practice to ensure you don’t run short.

3. Can I use this for metric units?

Currently, this calculator is configured for imperial units (feet, inches) which are standard in many regions. We are working on a version that will support metric units (meters, centimeters) in the future.

4. What do the mix ratios like ‘1:2:4’ mean?

This refers to the proportion of materials by volume. A 1:2:4 ratio means for every 1 part of cement, you use 2 parts of sand and 4 parts of coarse aggregate. Our calculator uses these ratios to provide the detailed material breakdown.

5. How accurate are the material weight calculations?

The weight calculations are based on standard average densities for dry materials. Actual densities can vary slightly depending on the source and moisture content. The provided weights are a very close estimate for procurement but may differ slightly from your supplier’s exact measurements.

Your Size vs. Sister Sizes

The Formula Behind the Fit

Our calculator uses an industry-standard method to determine your bra size. It’s a two-step process that combines your band and bust measurements.

  1. Band Size Calculation: Your underbust measurement is the starting point. In the US/UK system, if your measurement is an odd number, we round it up to the next even number. For example, a 29-inch underbust becomes a 30 band size. If it’s already even, it stays the same. This rounded number is your final band size.
  2. Cup Size Calculation: The cup size is determined by the difference between your bust measurement and your calculated band size (not your raw underbust measurement). Each inch of difference corresponds to a letter in the cup alphabet.
    Formula: Cup Size = Bust Measurement – Band Size
    • 1 inch difference = A cup
    • 2 inches difference = B cup
    • 3 inches difference = C cup
    • 4 inches difference = D cup
    • …and so on.

By combining these two calculated parts, you get your final bra size (e.g., 34C). Our tool then uses comprehensive conversion charts to show you your equivalent size in different international systems.

1. About This Tool

Welcome to our comprehensive Bra Size Calculator, a tool designed to empower you with the knowledge to find a comfortable and supportive bra. We understand that navigating the world of bra sizing can be confusing and frustrating. With inconsistent sizing across brands and countries, finding the right fit often feels like a guessing game.

5. FAQs

How often should I measure my bra size?

It’s a good idea to measure yourself at least once a year. Your bra size can change due to factors like weight fluctuations, pregnancy, exercise, and hormonal changes. If your bras start to feel uncomfortable, it’s a clear sign that it’s time to measure again.

What are sister sizes and why are they important?

Sister sizes are a group of bra sizes with the same cup volume. For example, a 32D, 34C, and 36B are sister sizes. They are important because if a bra’s band feels too tight or too loose, you can try a sister size to get a better fit while keeping the same cup capacity. The rule is: if you go up a band size, go down a cup size (e.g., from 34C to 36B), and if you go down a band size, go up a cup size (e.g., from 34C to 32D).

Why do my bra sizes vary so much between different brands?

This is a common and frustrating issue caused by a lack of universal sizing standards in the lingerie industry. Each brand uses its own models and patterns, leading to variations in fit even for the same labeled size. This is why our tool’s international conversion chart is so valuable, as it gives you a baseline for navigating these differences.

My calculated size seems wrong. What should I do?

First, double-check your measurements to ensure they were taken correctly (snugly for the underbust, loosely for the bust, with the tape measure level). If the measurements are correct, remember that this calculator provides a highly accurate starting point. Bra fit is also affected by breast shape (e.g., shallow, projected, full on top/bottom) and the style of the bra. Use the calculated size as your guide, and don’t be afraid to try the recommended sister sizes to fine-tune your fit.

Can I use this calculator for sports bras or bralettes?

This calculator is primarily designed for standard, underwired bras. Sports bras and bralettes often use more general sizing like Small, Medium, and Large. While your calculated bra size can help you find the right range in those charts (e.g., a 34C is often a Medium), you should always refer to the specific brand’s sizing chart for those types of garments, as their fit is very different.
