Here is a list of 4 free online deck board calculator websites. A deck helps you make outside space of your home more usable that you can use as extension of your house, entertain guests, gardening, eat outside, etc. Before creating a deck, you must know how many deck boards will be needed for it. These websites will help you for that. You can enter total area (length and width) for deck, board size, decking angle (if available), etc., and then get the results.

These websites provide some other good features also. For example, you can check estimated price of number of deck boards, number of hidden fasteners, screws needed, installation overview with a diagram showing number of deck boards, deck length and height, etc.

Let’s check these free online deck board calculators one by one.

Inch Calculator

Inch Calculator deck board calculation

Inch Calculator is one of the best websites for deck board calculation. It also lets you add estimated price per deck board and then it will show total price for number of deck boards needed. In addition to that, it can also show price for face screws and number of screws needed for deck.

The feature that I like a lot is it provides installation overview where it shows a diagram including number of deck boards, deck length and width, etc.

You can add input values like deck width and length, board width, board length, joint spacing, and price per board (optional). After that, it will give you the calculations or results related to number of deck boards, price, screws, etc.


Blocklayer website

Blocklayer website is a good competitor to other deck board calculators covered on this list. Its Deck and Floor Board Spacing and Quantify Calculator is quite good. Here is the link. You can add crucial input details which include deck width, board width, optimal gap, waste percentage, joist spacing, estimated cost, etc. Based on all these values, you will get the calculation.

The output shows how many deck boards with specific size are needed including the optimal gaps. A beautiful diagram is also presented for the output that is really good.
