Wood Chart - Live Sawn vs Plain Sawn vs. Rift & Quarter
When choosing a new hardwood floor, most homeowners focus heavily on the wood species, plank width, or stain color. However, there is an equally critical factor that determines how your floor will look, how it will age, and how it will handle changes in humidity: how the log was cut at the sawmill.
The milling angle changes the orientation of the wood’s annual growth rings relative to the face of the floorboard. This impacts everything from the visual grain pattern to the floor's overall dimensional stability. To help you choose the perfect fit for your home, let’s break down the four main types of lumber cuts used in hardwood flooring.
1. Plain Sawn (Flat Sawn)
Plain sawn is the most traditional and common milling method used for hardwood flooring. The log is sliced parallel to the growth rings in a straightforward, parallel sequence.
- The Look: It features a highly recognizable, traditional look with dramatic arches, loops, and swirls often referred to as a "cathedral" grain pattern.
- The Advantages: Because it utilizes the log highly efficiently, it produces the least amount of waste. This makes plain sawn flooring the most affordable and widely available option.
- The Drawbacks: The growth rings run horizontally across the width of the board (at a 0 to 35-degree angle). Because wood expands and contracts in the direction of its rings, plain sawn boards experience the most lateral (widthwise) movement. This means they are more prone to cupping, bowing, or gapping during seasonal humidity shifts.
2. Quarter Sawn
To produce quarter sawn lumber, the log is first cut into four equal quarters. Each quarter is then flipped back and forth and sliced radially from the center outward.
- The Look: Slicing across the growth rings at a 60 to 90-degree angle results in a very straight, tight, linear grain pattern. In certain species—most notably White Oak—this cut exposes the wood's medullary rays, creating beautiful, shimmering, or wavy highlights known as "ray flecks."
- The Advantages: It is exceptionally stable. Because the growth rings run vertically through the thickness of the board rather than across its width, any expansion or contraction happens vertically (which is unnoticeable) rather than horizontally. It is highly resistant to cupping and twisting.
- The Drawbacks: The milling process is labor-intensive and creates significantly more wood waste. Consequently, quarter sawn flooring carries a higher price tag and is harder to source in very wide planks.
3. Rift Sawn
Rift sawn lumber is manufactured using a unique milling process where each board is cut at a precise angle (typically 30 to 60 degrees, with 45 degrees being ideal) to the log's growth rings.
- The Look: Rift sawn produces an ultra-consistent, straight, and uniform "combed" linear grain. Unlike quarter sawn wood, the angle of the cut intentionally minimizes or eliminates ray flecks, providing a clean, flawless look.
- The Advantages: It offers the highest dimensional stability of any individual wood cut. Its uniform linear pattern makes it a favorite for modern, minimalist, and contemporary architectural designs where visual consistency is paramount.
- The Drawbacks: This method produces the lowest yield from the log and the most waste material. Because of the labor required and high waste factor, rift sawn is typically the most expensive wood cut on the market.
4. Live Sawn (Thru-Cut)
Live sawn is an old-world European method of cutting lumber where the sawmill slices straight through the log from one side to the other without turning it.
- The Look: Because it slices right through the log, a single live-sawn plank contains a mixture of all three previous cuts. The center of the board displays the cathedral grain of a plain cut, while the outer edges display the straight lines and ray flecks of rift and quartered cuts. It showcases the full natural character of the tree, including knots, sapwood, and heartwood variations.
- The Advantages: Live sawn utilizes nearly 100% of the log, making it highly sustainable and cost-effective. Because each board includes a high percentage of stable rift and quartered grain on its edges, live sawn planks are incredibly stable. This structural stability allows manufacturers to confidently offer live sawn flooring in striking wide-plank options (often 6 to 12 inches wide).
- The Drawbacks: Its varied, rustic, and character-rich aesthetic may not fit homes looking for a completely uniform or ultra-formal floor design.
Quick Comparison Summary
| Wood Cut | Grain Pattern | Relative Cost | Stability | Best For |
|---|---|---|---|---|
| Plain Sawn | Cathedral arches, swirls | $ (Budget) | Moderate | Traditional, Classic |
| Live Sawn | Mixed (Cathedral & Linear) | $$ (Luxury Value) | High | Rustic, Wide Plank |
| Quarter Sawn | Straight lines, ray flecks | $$$ (Premium) | High | Craftsman, Mission |
| Rift Sawn | Straight lines, uniform | $$$$ (Expensive) | Highest | Modern, Minimalist |
Which Wood Cut is Right for Your Project?
- Choose Plain Sawn if: You love the classic, wavy look of traditional hardwood floors, are working within a standard budget, and are installing standard-width planks (under 5 inches) in a climate-controlled environment.
- Choose Rift & Quartered if: You are looking for a high-end appearance, want to minimize seasonal gapping, or are planning to install solid hardwood over radiant heating systems. (Note: Because of how they are milled, rift and quartered cuts are often combined into a single blend by flooring manufacturers).
- Choose Live Sawn if: You want a striking, European-inspired wide-plank floor with unique rustic charm and natural wood character without sacrificing structural stability or breaking your budget.
