These sizes are estimates. We used the longest and the widest of 16 double jet ski trailers whose makers publish their sizes. So our answer may point you to a bigger space than you need. Measure your own trailer to be sure. How to measure your trailer
Outdoor works well for this one
A secured outdoor space with a good cover is plenty for most jet skis. Want it ready at the gate on Saturday morning? That’s what valet is for.

How we sized it
- Length needed: 17′ 9″ (estimate: the longest of 16 double jet ski trailers with published sizes) + 3′ to back in and close up = 20′ 9″.
- Width: 8′ 6″ (estimate: the widest of the same 16 trailers). A width up to 8′ 6″ never rules out a space.
- Indoor: every RV Storage Depot facility with indoor valet takes a jet ski on its trailer indoors, so height isn’t part of this answer.
- Specs: published trailer specifications from five makers, checked 2026-10-16.
- Last updated 2026-10-21.
