Hand-Holding Simulator: Estimate Hand Size and Preview a Grip

Two fields, then a pair of hands

Simply put, it is an upgrade of the earlier Hand Size Comparison Tool.

Hand-Holding Simulator solves a small, specific problem: you want a picture of two hands together, sized to the people involved, without measuring palms with a ruler. On the official page, you give gender and height. From those, the tool guesses an approximate hand size and uses that guess to simulate how the hands connect.

The page describes the job in one line: it infers hand size from gender and height, then simulates styles of holding hands. The creator’s own note stresses that the size is a rough automatic calculation, not a clinical measurement. The visible mode on the page is the lover’s hold, 恋人つなぎ. Notes on the release also point to a handshake, palms pressed together, and a one-tap way to share the result.

• Lover’s hold

  The grip labeled on the page, meant to show a romantic handhold once both sizes are estimated.

• Handshake

  A formal clasp using the same estimated hands, useful when you want a greeting instead of a couple’s grip.

• Palms together

  Hands pressed palm to palm, the prayer-style pose included alongside the other grips.

• Share

  A one-step share of the simulation so you can pass the picture along without rebuilding it.

What changed from the comparison tool

ｽﾃ。 framed this release as the higher-spec version of a past project, the Hand Size Comparison Tool. That earlier tool was about putting hand sizes next to each other. This one keeps the size estimate and adds the pose: the hands are not only scaled, they are shown holding, shaking, or pressed together.

You do not install anything. Open the page on qwertyaz111.github.io, titled 手繋ぎシミュレーター. There is no separate app, account step, or price listed on the page. The whole workflow is the form, the generated hands, and the option to share.

Rough on purpose, and not for sale

Please refrain from profit-making and commercial use.

Treat the result as a sketch. Height and gender drive a general hand size, which the creator described as approximate. Two people of the same height will not get a custom measurement of palm width, finger length, or grip strength. The simulation shows a plausible pairing, which is why it works for a playful preview and not for gloves, medical fitting, or product design.

The page also sets a use limit in plain text: refrain from profit-making and commercial use. Personal tries, including a couple comparing heights or a quick handshake preview, stay inside what the page invites. Packaging the image into ads, merch, or a paid service does not.
