The span of a triple LVL (Laminated Veneer Lumber) beam depends on several factors including the species and grade of the lumber, the load it will bear, and the spacing between supports.
As per general rule a triple LVL can span 20 to 24 inches per foot deep, so a triple 2×10 LVL can span 18 feet, while a triple 2×12 LVL can span 22 feet. In addition, a triple 14″ LVL can span 25 feet.
LVL (Laminated Veneer Lumber) Beams are comes in a range of sizes with a width of 1-3/4” (44 mm), depths from 5-1/2” to 24” (14-61 cm), and typical lengths between 16 to 48′ feet (4.88-14.63 m).
LVL standard thickness of 1-3/4 inches (one ply), 3-1/2 inches (2 ply), 5-1/4″ (3 ply) and 7 inches (4 ply). Common depth of LVL beam are 5 1/2″, 7 1/4″, 9 1/4″, 9 1/2″, 11 1/2″, 11 7/8″, 12″, 14″ 16″ & 18″ deep.
A triple 2×8 LVL typically refers to three 2×8 LVL beams stacked together side by side to form a single structural member. A triple 2×8 LVL beam has a nominal width of 6 inches and a nominal depth of 8 inches. So, it can also written as 6×8 LVL.
Here’s are table for span of triple LVL (Laminated Veneer Lumber):-
- A triple 2×6 (or 6×6, (3) 2×6) LVL (Laminated Veneer Lumber) beam can span 10 feet
- A triple 2×8 (or 6×8, (3) 2×8) LVL (Laminated Veneer Lumber) beam can span 15 feet
- A triple 2×10 (or 6×10, (3) 2×10) LVL (Laminated Veneer Lumber) beam can span 18 feet
- A triple 2×12 (or 6×12, (3) 2×12) LVL (Laminated Veneer Lumber) beam can span 22 feet
- A triple 2×14 (or 6×14, (3) 2×14) LVL (Laminated Veneer Lumber) beam can span 25 feet
- A triple 2×16 (or 6×16, (3) 2×16) LVL (Laminated Veneer Lumber) beam can span 30 feet
- A triple 2×18 (or 6×18, (3) 2×18) LVL (Laminated Veneer Lumber) beam can span 33 feet.
How far can a triple 2×8, 2×10, 2×12, 2×14, 2×16 & 2×18 LVL span
As per LVL span rule of thumb & general guideline, the depth of the LVL (Laminated Veneer Lumber) beam is range from 1/20th to 1/24th of span in inches and their width is 1/3 to 1/4 of the depth.
In general, a triple 2×6 LVL beam can span 10 feet, while a triple 2×8 LVL beam can span 15 feet. Likewise, a triple 2×10 LVL beam can span 18 feet, while a triple 2×12 LVL beam can span 22 feet. In addition, a triple 14″ LVL beam can span 25 feet, a triple 16″ LVL beam can span 30 feet, and a triple 18″ LVL beam can span 33 feet.
Here’s are table for how far can a triple 2×8, 2×10, 2×12, 2×14, 2×16 & 2×18 LVL span:-
| LVL size | Nominal Width | Nominal depth | Span in feet |
| A triple 2×6 or 6×6 | 6 inches | 6 inches | 10 feet |
| A triple 2×8 or 6×8 | 6 inches | 8 inches | 15 feet |
| A triple 2×10 or 6×10 | 6 inches | 10 inches | 18 feet |
| A triple 2×12 or 6×12 | 6 inches | 12 inches | 22 feet |
| A triple 14″ or 6×14 | 6 inches | 14 inches | 25 feet |
| A triple 16″ or 6×16 | 6 inches | 16 inches | 30 feet |
| A triple 18″ or 6×18 | 6 inches | 18 inches | 33 feet |
Conclusions:
Typically a triple LVL can span 20 to 24 inches per foot deep, so a triple 2×12 LVL can span 22 feet, a triple 2×10 LVL can span 18 feet, a triple 2×8 LVL can span 15 feet, a triple 14″ LVL can span 25 feet, a triple 16″ LVL can span 30 feet, and a triple 18″ LVL can span 33 feet.
