Kimonos for men are available in various sizes and should fall approximately to the ankle without tucking. A woman's kimono has additional length to allow for the ohashori, the tuck that can be seen under the obi which is used to adjust the kimono to the individual wearer. An ideally tailored kimono has sleeves that fall to the wrist when the arms are lowered.

Kimonos are traditionally made from a single bolt of fabric called a tan. Tan come in standard dimensions—about 14 inches wide and 12½ yards long—and the entire bolt is used to make one kimono. The finished kimono consists of four main strips of fabric—two panels covering the body and two panels forming the sleeves—with additional smaller strips forming the narrow front panels and collar. Historically, kimonos were often taken apart for washing as separate panels and resewn by hand. Because the entire bolt remains in the finished garment without cutting, the kimono can be retailored easily to fit a different person.

The maximum width of the sleeve is dictated by the width of the fabric. The distance from the center of the spine to the end of the sleeve could not exceed twice the width of the fabric. Traditional kimono fabric was typically no more than 36 centimeters (14 inches) wide. Thus the distance from spine to wrist could not exceed a maximum of roughly 68 centimeters (27 inches). Modern kimono fabric is woven as wide as 42 centimeters (17 inches) to accommodate modern Japanese body sizes. Very tall or heavy people, such as sumo wrestlers, must have kimono custom-made by either joining multiple bolts, weaving custom-width fabric, or using non-standard size fabric.

Traditionally, kimonos are sewn by hand, but even machine-made kimonos require substantial hand-stitching. Kimono fabrics are also frequently hand made and hand decorated. Various techniques such as yūzen dye resist are used for applying decoration and patterns to the base cloth. Repeating patterns that cover a large area of a kimono are traditionally done with the yūzen resist technique and a stencil. Over time there have been many variations in color, fabric and style, as well as accessories such as the obi.

The kimono and obi are traditionally made of silk, silk brocade, silk crepes (such as chirimen) and satin weaves (such as rinzu). Modern kimonos are also widely available in less-expensive easy-care fabrics such as rayon, cotton sateen, cotton, polyester and other synthetic fibers. Silk is still considered the ideal fabric.

Customarily, woven patterns and dyed repeat patterns are considered informal; Formal kimonos have free-style designs dyed over the whole surface or along the hem. During the Heian period, kimonos were worn with up to a dozen or more colorful contrasting layers, with each combination of colors being a named pattern. Today, the kimono is normally worn with a single layer on top of one or more undergarments. The pattern of the kimono can also determine in which season it should be worn. For example, a pattern with butterflies or cherry blossoms would be worn in spring. Watery designs are common during the summer. A popular autumn motif is the russet leaf of the Japanese maple; for winter, designs may include bamboo, pine trees and plum blossoms.

A popular form of textile art in Japan is shibori (intricate tie dye), found on some of the more expensive kimonos and haori kimono jackets. Patterns are created by minutely binding the fabric and masking off areas, then dying it, usually done by hand. When the bindings are removed, an undyed pattern is revealed. Shibori work can be further enhanced with yuzen (hand applied) drawing or painting with textile dyes or with embroidery; it is then known as tsujigahana. Shibori textiles are very time consuming to produce and require great skill, so the textiles and garments created from them are very expensive and highly prized.

Old kimonos are often recycled in various ways: altered to make haori, hiyoku, or kimonos for children, used to patch similar kimono, used for making handbags and similar kimono accessories, and used to make covers, bags or cases for various implements, especially for sweet-picks used in tea ceremonies. Damaged kimonos can be disassembled and resewn to hide the soiled areas, and those with damage below the waistline can be worn under a hakama. Historically, skilled craftsmen laboriously picked the silk thread from old kimono and rewove it into a new textile in the width of a heko obi for men's kimono, using a recycling weaving method called saki-ori.
