A shelf in the house is of utmost importance. No house storage design is complete without them. Therefore one needs to pay great attention while designing the racks and also choosing its materials. Shelves add beauty to the interiors of the house because people can use it to place beautiful ornaments. Outdoors it can be of utmost importance for storing tools and equipment. People also use such shelves for decorating their garden by hanging and placing pots on them; therefore, shelves are an integral part of home decoration. But before making a shelf, one must consider two things, the material’s span capacity, and their placing.

Considerations For Making A Shelf

A carpenter needs to keep in mind two things before he starts making a shelf. Firstly he must make sure that the material of the shelves has sufficient span capacity — secondly, space between the two shelves. The vertical spacing between the two shelves depends upon the types of objects one wants to keep on them. Each shelf has a span limit. This means that if one keeps heavy items on the shelves without knowing their span capacity, it is more likely that the shelves will sag under the weight. Span means the space between the two shelf supports. Its limits depend upon the sturdiness of the wood. If the wood is stronger, then one can keep more space between the supports. A short span limit means that one can hold more massive objects on them and vice-versa.

Plywood Shelf Span

A ¾ ” thick plywood is appropriate for making shelves. And the span of the ¾” plywood can be not more than 36″. If the distance between the two supports or the span is high, the plywood is likely to sag.

1xLumber Board

A 1xLumber board is ¾” thick. It is an active board but has a fewer knot that can make them weak. Therefore the span between 1×10 lumber should not be more than 24 inches else. It is more likely to sag.

2xLumber Board

A 2×10 lumber board is 11/2″ thick. Therefore it is a high-grade board. It has very fewer knots and is high in quality. Consequently, the span between 2×10 lumber boards can be 48 inches. Therefore it is appropriate for keeping middleweight objects.

Particle Board Shelves

Particleboard comprises of sawdust and other by-products of wood. The materials are bonded together using glue. A 5/8 inch thick board can have a span of 24 inches, and a ¾ inch particle board can have a span of 28 inches. Therefore one can use it for lightweight objects.

Conclusion

Span is a small calculation that one must do before designing a board and shopping for the same. A harder board can have a full span, and a lighter board can have a smaller span. Therefore the users must before placing the object on the shelves to check the thickness of the board and the span. One can then use it for either decorating the house or storing the heavy objects.
