The Basics
Normally, the sizes of the boxes are measured on the basis of their inner dimensions unless the customer has specifically mentioned otherwise. The size of the inner dimensions of the boxes required for any organization or the opening of the assembled boxes. The longer portion of the two ends of a box is takes as the “length” of the box, while the shorter part is taken as the “width” of the box. The portion perpendicular to the width and length is taken as the “depth” of the box. customer will be decided on the basis of the contents which are to be stored or transported in the box. As per the method followed in the US, the dimensions are listed in the sequence of – Length (L) x Width (W) x Depth (D), this is the domestic format. But the format used internationally is Length (L) x Breadth (B) x Height (H). These dimensions are decided as per

How to measure a box – Quick Guide Line
From the position of looking at the opening of the box, the longest portion is measured first, using a measure tape and then it is placed at the bottom of the box, at least an inch from the back wall and then the measurement from left to right is taken. The entire process is redone in the same way for measuring the shorter width panel. After this, one side of the box flap is folded inward so that it is in a position perpendicular to the vertical side of the wall and then the measuring tape is placed at the edge of the flap and extended till it reaches the inner flap which is at the bottom of the box as can be seen in the illustration. This process helps to determine the depth of the box.

The mailer style boxes which have die cut boxes, one piece boxes have the same measuring procedure but they do not have flaps when they are assembled as they come with tuck-in tops. So, in these boxes, the inside back panel consists of a score line which is the crease that separates the lid from the back panel which determines the depth. While for measuring the width of the die cut box, there are score lines on the inside of the lid, and measuring between these score lines gives the width of the box. While to find the box length; place the measuring tape at the bottom of the box, one inch away from the back panel and measure the area from left to right.

Flutes
Corrugating is defined as the imparting of wave-like shape to a paper.

Kraft paper or fluting media paper is passed through heated corrugated rolls to obtain continuous rolling, wave-like shape. These are called flutes. Observed vertically, they form a row of columns – a basic structural form capable of supporting great weight. Viewed horizontally, flutes are arches- another basic structural form capable of providing cushioning properties. The combination of columns and arches pro –duce a material far stronger then the paper from which it is converted.

Depending on the strength properties required, different types of flutes are used. Generally four different types of flutes, known as A,B,C and E are available.

Box Strength
The process of Corrugation involves the shaping the paper into the shape of a wave. The fluting media paper or the kraft paper is passed via heated corrugated rolls for getting a wave like continuous rolling shape, which are known as flutes. When they are viewed vertically they resemble a row of columns which are the basic structural form which can support a high amount of weight. While from a horizontal view, these flutes are arches which form the basic structure that has cushioning properties. This amalgamation of arches and columns form a product which is much stronger than the paper used for making it. The type of flute which will be used depends on the properties There are four types of flutes manufactured in the market, and they are named as – A, B, C, D and E. The Box strength is divided into three categories – Three Ply, Five Ply and Seven Ply. When the fluted paper is stuck with the flat sheet of paper then it becomes a 2-ply corrugated board. When one fluted paper is stuck with two flat papers then it gets converted into 3-ply corrugated board. In the same way the 9-ply, 7-ply and the 5-ply corrugated boars are also manufactured by attaching several flat papers to the fluting paper.

The corrugated boards are easy to cut into shapes and they can be folded into any desired directions. They can be created to produce containers, cases, cartons, boxes, fillers, supports and so on. These boxes restrict the movements and provide an inner cushioning to the products. The different forms and the shapes which have been mentioned above are known as “corrugates boxes” to sever the need for brevity. This corrugated board serves as great packaging materials and they offer different packaging ways to suit the requirements of the different companies.
