The Flexibility Scale
The F-Scale explained
The F-Scale rates how soft or firm a wash feels — from pourable liquid (F0) to a classic hard bar (F10). A plain language for texture — so you can choose Contour by how it feels, not by marketing labels.
Texture First
Softness isn’t a vibe. It’s a number you can shop.
Most bars are sold as “moisturizing,” “exfoliating,” or “natural” — words that say little about what happens when warm water hits your hands. The F-Scale fills that gap.
01 · Why it exists
We needed a shared language for feel
When we started Contour, every conversation drifted into metaphor: “kind of soft,” “almost like a gel,” “firmer than drugstore soap.” That language doesn’t help someone shopping for the first time — and it doesn’t help us craft the next density.
So we built the F-Scale the way a volume knob works: one continuum, clear endpoints, and intentional stops in between. Lower numbers feel softer and more liquid. Higher numbers feel firmer and more classic-bar. The middle is where Contour launches.
Think of the F-Scale as a volume knob for texture. F0 pours like body wash. F10 is a traditional rigid bar. Numbers in between describe how much the formula flexes in your hands. Once you can name the sensation, you can choose it on purpose — and tell us when something on the roadmap would fit you better.
02 · How to read it
One continuum. Clear stops. No jargon.
Read the F-Scale left to right the way you’d turn a dial: from pourable comfort toward solid structure. You’re not scoring “quality” — you’re locating give in the hand when the formula is wet, and how composed it stays when it rests on a dish.
Contour products list density the same way a size chart lists size. Scent is atmosphere. Density is feel. Keeping those separate is intentional, so shopping stays clear.
F0
Liquid end
Pours, pools, coats — the familiar comfort of body wash from a bottle.
F5
Contour launch
Flexible wet or dry — the balanced middle we ship today.
F10
Hard-bar end
Classic rigid soap — firm from first touch to the last wash.
03 · Soft to firm
The two ends define everything in between
Before you pick a Contour density, it helps to feel the poles in your mind. F0 is pure liquid familiarity — nothing to hold, nothing to flex. F10 is the opposite: a bar that stays composed, barely yielding even under warm water.
Every number between those poles is a deliberate compromise: more pourable comfort, or more bar structure. Contour isn’t trying to invent a third category of soap. It’s mapping the spectrum you already know onto something you can order by name.
F0 · Soft end
Pure liquid
Imagine body wash from a bottle: it pours, pools in the palm, and coats skin quickly. There’s no “bar moment” — no molding, no resting on a dish, no aging of a solid form.
On the F-Scale, that’s the softest reference. If that’s your everyday comfort, you’ll probably lean toward lower Contour ratings when they ship — F1 or F3 — while F5 is a step firmer but still designed to give.
F10 · Firm end
Classic hard bar
A traditional rigid bar holds firm from the first wash. Minimal flex, clear edges, and a dish presence that barely softens between showers.
If that structure is what you love, F7–F9 Contour ratings will eventually meet you closer to home. F5 is softer than that ideal — but it’s the same Texture First idea, and the best way to feel how our scale works until denser options arrive.
04 · Why F5
We launched in the middle on purpose
F5 is Contour’s launch density because it’s the clearest demonstration of Texture First: flexible enough to mold in the hand whether wet or dry, sturdy enough to hold form through 30+ washes — without cracking, crumbling, or melting into mush.
Starting at the middle also makes the rest of the scale teachable. Once you’ve felt F5, “softer” and “firmer” stop being abstract. You have a reference in your hands.
That doesn’t mean F5 is a compromise forever. Softer and denser Contour ratings are on the roadmap. F5 is the foundation — the bar we designed so the scale itself makes sense.
05 · How to choose
A practical path from “curious” to Contour
You don’t need to memorize every marker. You need a starting point that respects how you already wash — then an honest next step if Contour isn’t a perfect first match.
- 01
Name your current comfort
Do you reach for a bottle, a hard bar, or something in between? That answer alone usually lands you soft, firm, or middle on the F-Scale.
- 02
Picture the wet moment
When soap is in your palms under warm water, do you want foldable give, a clear bend that still feels like a bar, or almost no flex at all?
- 03
Start with what’s shipping
Today that’s Contour at F5. If your quiz or instinct lands softer or firmer, try F5 as a reference — or wait for roadmap densities and join Contour Club for the rhythm.
- 04
Separate scent from density
Every Contour scent shares the same F5 feel. Pick fragrance for atmosphere. Keep density for how the bar behaves. That split keeps Contour shopping simple.
06 · What’s next
More densities. Same scale. Same Texture First promise.
The F-Scale isn’t a one-product gimmick. Softer Contour ratings (toward liquid comfort) and firmer ratings (toward classic bar structure) will populate the same continuum — so when you reorder, you’re still speaking the same language.
Contour Club exists for people who already know they’ll go through Contour on a rhythm: two bars a month, seasonal editions when they drop, and member pricing as the catalog grows. The free email list stays separate if you only want notes.
Until denser options ship, F5 remains the essential — the bar that teaches the scale and the wash we stand behind today.
