How much Silica Gel do I need?

This is the most common question we get asked. The following information answers that question and provides customers with the tools to calculate their own quantity requirements

The calculator below is what we use when we're asked "How much do I need?" ... it's now available for you to use.

Step 1. Enter the dimensions of the space you're protecting into the calculator utility below to calculate the grams of Silica Gel required

Tip - it does not matter which side of your 3 dimensional object is entered into which field below (this is why we have not named the 3 sides and just numbered them instead)

Step 2. Now that you know how much Silica Gel you need head over to the Shop to buy the correct size

Here is an example of using the calculator above and selecting the right Silica Gel product from the Shop

John's boxes he is putting into storage are 70cm high by 40cm wide by 35cm deep (70 x 40 x 35cm) John enters those measurements into the calculator (in any order) and gets the result that he requires 98 grams of Silica Gel. Now that John knows how much Silica Gel he needs he heads over to the Shop to look for the right size product

John uses the quick links at the top of the Silica Gel sachets category and sees that the closest size to 98 grams are 100 gram sachets so John goes ahead and purchases the 100 gram sachets as he only intends to use 1 Silica Gel sachet for each box

Alternative size sachets that John could have opted for to make up the 98 grams are 2 x 50 gram sachets per box, or 3 x 35 gram sachets etc. In fact when protecting a contained space the size of John's box it is common to use 2 or more evenly distributed smaller sachets as they will reduce moisture levels faster than 1 larger sachet
