how to figure amount of wax for candles


Choosing the Right Amount of Wax for your Candles


Creating your own candles can be a fulfilling and enjoyable hobby that allows you to express your creativity while producing beautiful and functional items. However, when it comes to making candles, it's crucial to understand how much wax you'll need to ensure a successful outcome. Determining the amount of wax required for your candles will not only save you from wastage but also ensure that your candles burn evenly and efficiently. In this article, we will delve into the intricacies of figuring out the ideal amount of wax for your candle-making endeavors.

Factors Influencing Wax Amount Selection

Determining the right amount of wax for your candles depends on various factors. Understanding these factors is essential to ensure the best results. Let's take a closer look at each one:

Candle Size and Shape

The size and shape of your candle play a significant role in determining the amount of wax needed. Larger candles with more surface area will require more wax to fill the mold properly, while smaller candles will obviously require less. Additionally, container candles, which are poured into containers with sides, require less wax compared to pillar candles, which are freestanding and need to be filled entirely.

To calculate the wax quantity needed for a container candle, measure the inside volume of the container using water and then convert that to ounces or milliliters. As a general rule of thumb, make sure to leave at least half an inch of empty space at the top to allow for the proper burning of the candle.

For pillar candles, you will need to use the mold's volume measurement. It's crucial to note that larger molds often have thicker walls, which can influence the wax amount needed to complete the candle.

Desired Burn Time

The desired burn time also plays a role in determining the amount of wax required for your candles. The longer you want your candle to burn, the more wax it will need. Wax consumption during burning depends on various factors such as wick size, fragrance, dye, and the candle's diameter. Keep in mind that adding fragrance or dye to your candles may decrease the burn time slightly.

If you want to calculate the wax amount based on burn time, you will need to run a few tests. Start by pouring a measured amount of wax into your chosen mold or container, then trim the wick to the desired length. Light the candle and note the time it takes to burn until the desired point, whether it's halfway, three-quarters, or fully melted. Based on the burn time recorded, you can then adjust the amount of wax for subsequent candles accordingly.

Wax Density and Type

Different types of waxes have different densities, which means that they weigh different amounts for the same volume. It's essential to know the density of the wax you are using to calculate the exact amount needed. Beeswax, soy wax, and paraffin wax are some commonly used options, each with its own density. Make sure to check the wax's specifications or consult the manufacturer for accurate density information.

To calculate the exact wax amount based on density, you can use the formula: weight (in grams) equals volume (in cubic centimeters) multiplied by density (in grams per cubic centimeter). By plugging in the desired weight, you can then determine the necessary volume of wax required.

Special Considerations for Different Candle Types

When it comes to specific candle types, there are additional factors to keep in mind while determining the wax amount required. Let's explore these considerations below:

1. Votive Candles: Votive candles are small, cylindrical candles typically burned inside a votive holder. As they are relatively small, the amount of wax needed is usually between 1.5 to 2 ounces (40-56 grams).

2. Taper Candles: Taper candles are long, slender candles burned in pairs. They require less wax compared to other candle types, with most taper candles requiring around 0.75 to 1 ounce (21-28 grams) of wax per inch of height.

3. Tealight Candles: Tealight candles are small, self-contained candles. They typically require approximately 0.5 to 1 ounce (14-28 grams) of wax per candle, depending on their diameter and desired burn time.

4. Floating Candles: Floating candles are designed to float in water, often used in decorative arrangements or centerpieces. As they have a broader surface area, they require more wax. The exact amount depends on the size and shape of the mold, but a general guideline is 2 ounces (56 grams) of wax per candle.

5. Novelty and Shaped Candles: These candles come in a variety of shapes, such as animals, flowers, or objects. The wax amount needed depends heavily on the size and intricacy of the mold. Generally, use the water displacement method mentioned earlier to calculate the required wax volume.


Calculating the ideal amount of wax for your candles is a crucial step that determines the quality and efficiency of your end product. Consider factors such as candle size and shape, desired burn time, wax type and density, as well as any specific considerations for different candle types. By paying attention to these elements and conducting tests, you can ensure that your candles burn evenly, providing both the right ambiance and value for your efforts. Enjoy the process of experimenting with different amounts of wax to create unique and beautiful candles tailored to your preferences.
