# The Ultimate Guide to Calculating the Size of Your Water Tank

When it comes to choosing a water tank, one of the most crucial factors to consider is the size. If you choose a tank that’s too small, you’ll run out of water during emergencies or periods of heavy use. If you choose a tank that’s too large, you’ll end up wasting money on unnecessary storage space. So how do you calculate the size of your water tank? In this blog post, we will provide an easy-to-use calculator that will help you find the perfect size for your needs!

## How much water tank capacity do I need?

Calculating the size of your water tank is an important first step in ensuring you have enough storage capacity to meet your needs. To calculate the tank capacity, you’ll need to know two things:

1) The area of your roof – this will tell you how much water can be collected from rainfall

2) Your average water usage – this will tell you how much water is needed daily

Once you have this information, you can use our tank sizing calculator to determine the size of the water tank that best fits your needs. Simply enter your roof area, and average water usage, and click “Calculate” to get an estimate of the optimal water tank size.

### How can I estimate my water intake?

To accurately calculate the size of your water tank, you’ll need to estimate your average daily water intake. This can be done by adding up all the water that is used in a typical day, including drinking and cooking, toilet flushing and laundry. Once you have this figure, you can use it as input in our tank sizing calculator.

### How much rainwater does a family of four need?

The amount of rainwater needed for a family of four depends on their daily water usage. As a rule, each person needs around fifty litres of water per day, so a family of four will need an estimated two hundred litres. However, this figure can vary depending on the climate and individual lifestyle choices. To get an accurate figure, consider your household’s water usage and use the tank sizing calculator to determine the optimal size for your water tank.

### What type of water tank should I get?

In addition to considering the size of your water tank, you also need to think about the material it’s made from. Several types of tanks are made from varied materials and offer varying levels of durability and storage capacity. The most common types of tanks are plastic, metal, and concrete tanks. Plastic tanks are the least expensive option but don’t last as long as the other materials. Metal and concrete tanks typically cost more upfront but can withstand harsher climates and will last much longer.
