What Size Sex Wedge Should You Get? A Sizing Guide

If you're wondering what size sex wedge should i get, there's no official height-based sizing chart to check against, but the three core Liberator sizes map cleanly onto three real use cases: the compact Jaz for travel and smaller spaces, the standard Wedge for most people and most positions, and the taller Ramp for more height, more support surface, and taller users. Here's how the real dimensions break down and how to actually pick.

The three sizes, by real dimensions

These are the manufacturer's published dimensions, checked directly against the current listings, not estimates.

How height and body size actually factor in

Neither Liberator nor any major competitor publishes a height-based sizing chart, so this is practical guidance rather than an official recommendation. The variable that matters most isn't height on its own, it's how much of your body the piece needs to support and at what angle:

Shorter or more compact users, or anyone prioritizing storage and travel: the Jaz's smaller 6" height gives a gentler, shallower angle in the most compact footprint of the three.

Most people, most of the time: the standard Wedge's 7" height and 24" width is the reference size the rest of the category is built around, and it's the right starting point if you're not sure which way to lean.

Taller users, or anyone who found the Wedge's angle too shallow: the Ramp's 12" height and 34" length change more of the overall geometry, not just the tilt, which matters more as user height increases and a shallower wedge starts to feel insufficient.

What actually changes between sizes

The height (6", 7", or 12") sets the angle: taller pieces create a steeper, more dramatic incline. The length and width set how much of your body rests on the foam versus your own arms and legs holding the position. Going up in size trades portability and storage for more support surface and a more pronounced angle, not the other way around.

Checking fit against your bed and storage space

Since there's no chart to check yourself against, the two practical measurements that actually matter are your mattress height and your storage space, not your own height or weight:

Mattress height relative to the piece. A taller Ramp (12") makes the biggest difference on a low platform bed or a mattress-on-floor setup, where a shorter wedge may not create much of an angle at all. On a taller bed with a boxspring, the standard Wedge's 7" is usually enough to create a real, noticeable tilt.

Where it lives when you're not using it. The Jaz is built to disappear into a closet shelf or a suitcase; the Ramp, at 34" long, needs real closet floor space or under-bed clearance. If storage and discretion matter more than a dramatic angle, that alone is a reason to size down rather than up, independent of height or body size.

Using more than one size together. Some couples keep both a Wedge and a Jaz, or a Wedge and a Ramp, and combine them for different positions rather than treating the purchase as a single either/or choice. There's nothing unusual about owning more than one size once you know which positions you use most.

If you're still unsure

Start with the standard Wedge. It's the size the rest of the line is calibrated against, the most reviewed and established option, and the easiest to size back down (Jaz) or up (Ramp) from once you know which direction you actually want to go. Check current price on Amazon →

FAQ

Is there an official sizing chart based on height? No. Neither Liberator nor comparable brands publish a height-based sizing chart. The three core sizes (Jaz, Wedge, Ramp) map to compact, standard, and taller/more-support use cases based on their published dimensions.

What size should a taller person get? The Ramp, generally. Its 34"L x 24"W x 12"H dimensions provide more support surface and a steeper angle, which tends to matter more as height increases and a shallower wedge feels insufficient.

Is the Jaz just a smaller Wedge? Yes, functionally. At 14"L x 18"W x 6"H it's more compact and travel-friendly than the standard Wedge (14"L x 24"W x 7"H), with a correspondingly gentler angle.

Should I just buy the biggest size to be safe? Not necessarily. A larger size means a more dramatic angle and a bigger storage footprint, not automatically "better" support. The standard Wedge is the calibrated middle ground most people should start with; see our Liberator Wedge review for the full breakdown.

Does my mattress height change which size I should get? Yes. A low platform bed or a mattress on the floor gets more benefit from the taller Ramp, since a shorter wedge may not create much of a visible angle at all. A taller bed with a boxspring usually gets a real, noticeable tilt from the standard Wedge's 7" height already.
