What Size Log Splitter Do I Need? A Quick Guide Based on Log Type & Usage

If you’ve ever found yourself overwhelmed by the tonnage options when shopping for a log splitter, you’re not alone. Choosing the right size log splitter is critical for getting the job done efficiently—and safely. Whether you're prepping firewood for winter or clearing out trees after a storm, this guide will help you figure out exactly what you need.

Why Size Matters

Log splitters are rated by tonnage, which refers to the amount of force they apply to split a log. Too little power, and the machine will struggle—or fail—to split the wood. Too much, and you may overspend on a machine that’s overkill for your needs.

Factors to Consider When Choosing a Log Splitter

1. Log Size (Diameter & Length)

• Small logs (under 6" diameter): 5–7 ton splitter

• Medium logs (6"–12" diameter): 10–20 ton splitter

• Large logs (12"+ diameter): 20+ ton splitter

2. Wood Type

• Softwoods (pine, fir, spruce): Easier to split, lower tonnage works fine.

• Hardwoods (oak, hickory, maple): Denser, needs more force—think 20+ tons.

3. Frequency of Use

• Occasional/Weekend Use: Smaller electric or manual splitter may suffice.

• Seasonal Heavy Use: Go with a mid- to high-tonnage model.

• Commercial/Professional Use: You’ll want at least a 25-ton gas-powered unit.

Electric vs. Gas Log Splitters

• Electric Splitters (5–10 tons): Lightweight, quiet, great for small logs and indoor use (garage/shed).

• Gas-Powered Splitters (10+ tons): More powerful and mobile, perfect for outdoor use and tougher jobs.

Horizontal vs. Vertical Splitters

• Horizontal Splitters: Great for smaller logs and frequent use.

• Vertical Splitters: Ideal for large, heavy logs you don’t want to lift.
