When selecting a softener you also want to pay attention to salt efficiency during the recovery and select a unit with a higher capacity than you need to maintain high efficiency.

Select the number of people that live in your home.
Water softeners are ion exchange systems designed to remove scale forming calcium and magnesium ions prior to boiler cooling and reverse osmosis systems.
By default the average water usage per person is set at a conservative 50 gallons per day.
Ideally a water softener should be sized so that it does not regenerate any more often that every three days wastes water and salt nor go longer than 14 days before regenerating can cause compacting of resin and fouling with sediment or iron.
How to calculate the resin capacity.
Before to calculate the capacity of the water softener softening plant to choose how much water to be softened.
10l softener 1660l of hard water 20l softener 3300l of hard water based on 300ppm also written as 300caco3mg l the volume of softened water required per day.
A water softener with low softening capacity would be suitable for 2 3 people but a low softening capacity in a home of 4 or more people will be expensive to run and because it will be working harder increase its wear and tear and longevity.
Use the calculator below and get a rough idea on the grain capacity required to sufficiently soften your water.
Need to find out the size or capacity of a water softener for your home.

Capacity is important when sizing configuring or troubleshooting a softener.
Water softener capacity calculation.
This is often accomplished by selecting the smallest softener filter model that can provide adequate capacity to meet your daily water usage.
The regeneration volumes for our softeners are based on 300ppm which indicates very hard water.
In this case 100m3 to be softened at 400 ppm of feed hardness to 5 ppm.
There are conditions that would create a need for a larger unit.
Therefore unless your water hardness is 300ppm you need to use a conversion factor.
Calculator assumptions usable softener resin capacity is 32 000 grains per ft 3 at 15 lbs per ft 3 salt charge the maximum flow rate for water softener resin is 7 gallons per minute per ft 3 softener is 65 full of resin beads if you do not know how hard your water is you can use this map to get a rough idea.
Water softener capacity calculation for the majority of homes our 32 000 grain unit 1 cubic foot of resin is more than enough capacity.
The size of the softener is mainly determined by water hardness and water consumption in your household.
