Buying a trailer for a side-by-side is a fitment problem first and a preference problem second. Get the width wrong and nothing else matters. Here is the decision path, followed by links to exact-machine math.
Width: the decision that decides the rest
Most modern sport and utility side-by-sides measure 60–64 inches wide — mirrors and tires included. On a 5-foot (60") deck, that is zero margin or negative. The 6.5-foot deck (78") gives 14–18 inches of walk-around and strap room. This is why nearly every UTV customer lands on our 6.5-wide models, and why we would rather tell you that plainly than sell you a 5x10 you will fight every weekend.
Length and weight
- Two-seat utility machines (Ranger, Defender, Mule): typically 118–122" long — a 12-ft deck fits with margin; 14-ft is comfortable.
- Crew cabs and 4-seaters: 140–160" long — plan on 14–16 ft of deck.
- Weights run roughly 1,200–2,000 lb dry. Single-axle payload (~2,000–2,300 lb on our line) covers lighter machines with little margin; tandems carry any of them with thousands of pounds to spare, plus brakes.
Per-machine math
The fitment guides run deck-fit and payload margin for specific machines with cited dimensions: Polaris Ranger, Can-Am Defender, Kawasaki Mule, and Honda Pioneer. If your machine is not listed yet, the sizing logic in the sizing guide gets you there.
The options that matter for machines
- A ramp you will actually use: bi-fold vs. stowaway covers the trade.
- Tie-down points at four corners of the machine, not the trailer corners — cross bars and D-rings are cheap insurance.
- Consider tandem for sport machines: higher approach speeds onto the deck reward the stability.
- Open or enclosed for a UTV?
- Open is cheaper, lighter, and easier to load; enclosed protects from weather and theft and doubles as storage. If the machine lives outside anyway, open usually wins on value.
- Will a sport UTV’s low clearance clear the ramp break-over?
- Lowered sport machines can scrape steep ramp angles. Longer ramps reduce the angle; the fitment guides flag break-over where relevant.
