How much oil a tank can hold is always measured in gallons. The most popular oil tank size for single-family homes is 275 gallons. If you have a measuring tape, start by measuring the width, height and depth of the exterior of the tank. Check the measurements below to see the capacity of your tank:
| Tank Dimensions | Tank Size |
| 27x44x60 | 275H |
| 44x27x60 | 275V |
| 44x27x72 | 330H |
| 27x44x72 | 330V |
| 48×72 | 550 |
| 48×130 | 1000 |
Next, you can determine how much heating oil is currently in your tank by gathering a long, clean measuring stick or pole. Place the clean stick into the tank and measure the number of inches the oil hits on the stick. This shows you how much oil is currently in your tank and can be used as a guidepost for placing your next heating oil order. The size of your tank is critical to the accuracy of your order and to ensure a seamless delivery process.
