What grain means
Grain is the surface pattern of a leather: the pores, marks, wrinkles and texture you can see on the outside. Grain can come from the animal, from processing such as tumbling, or from a pattern pressed into the surface. Knowing which one you are looking at tells you how the leather will age and how well it will hide wear.
Natural grain: pores, wrinkles and species signs
Natural grain is the animal’s own pattern. It is irregular and never repeats. On full-grain leather you can see pores, fine wrinkles and marks, which vary across the hide.
Species leave distinct signs. Pig pores go in groups of three. Ostrich has raised quill bumps on the back. Goat has a fine, pebbly grain, and calf has a very fine, smooth grain. What types of animal leather there are covers more of these differences.
Pebble grain: milled or embossed
Pebble grain has round, raised bumps. It can be made in two ways:
- Milled or tumbled: the leather is tumbled in a drum, which relaxes the fibres and raises a soft, natural, irregular pebble.
- Embossed: a pattern is pressed into the surface with a heated plate in a press. The result is uniform and often repeats.
Pebble grain can be natural or embossed, so the word alone does not tell you which. Check the surface.
Pebble and embossed textures hide scratches and creases better than smooth leather. Heavily embossed leather is often corrected grain.
Embossed grains
Embossing presses a pattern into the surface with heat and pressure. Embossed patterns are usually even and repeating, which makes them easier to spot once you know what to look for. Embossing can make a plain hide look like a more expensive one, so check the grain before you buy.
Embossed patterns are not fake in themselves, since they are often applied to real leather. They are not natural grain either, and the listing should say so.
Scotch grain and boarded grain
- Scotch grain is a heavy embossed pebble pattern, often seen on country brogues and other shoe uppers.
- Boarded grain is raised by folding the leather grain to grain and rolling it with a cork board. Box calf is often boarded in two directions, which gives a pattern of fine, raised lines.
Crinkle, crackle and shrunken grain
- Crinkle or crackle is a wrinkled texture from shrinking during processing or from embossing. Some crinkle finishes are designed to look aged, much like antiqued leather.
- Shrunken grain uses chemical shrinking agents to make a deep, bubbled grain.
Saffiano and epi
These are named patterns, not leather types.
- Saffiano is a crosshatch pattern pressed into leather and coated with wax. It is closely associated with Prada.
- Epi is a wavy embossed pattern introduced by Louis Vuitton in the 1980s.
Both are textures, and both can be applied to different base leathers.
Croc and snake prints on cowhide
Many croc and snake prints are embossed onto cowhide. Real scales vary in size across the skin, while embossed prints tend to repeat. Embossed croc-print leather is not crocodile. Luxury and exotic leathers covers real exotic skins and how they differ from prints.
Smooth does not mean full grain
A smooth surface can be full grain, but it can also be corrected grain that has been sanded and coated, or a synthetic. Smoothness alone does not tell you the grade. Look for natural marks, and check the listing for the grade and finish. Types of leather explained sets out the grades.
Telling natural from embossed
Look for these signs:
- Irregular pattern: natural grain varies from place to place and never repeats.
- Depth and evenness: embossing often looks shallow and uniform.
- Consistency: natural marks change across the piece, while a stamped pattern looks the same on every panel.
If you are unsure, ask the seller whether the grain is natural or embossed.
Which textures suit which projects
- Pebble and embossed grains hide scratches and creases, which suits everyday bags and items that take daily knocks.
- Smooth full grain shows natural character and develops patina, which suits items you want to age.
- Suede and nubuck have a velvety nap that needs its own care. Suede vs nubuck explains the difference.
