Plush Eye Placement Calculator

Eye placement is the biggest single factor in whether a plush toy looks cute or off-putting. There is real visual science behind this.

Cute (neoteny) style

Human brains are wired to find baby-like proportions appealing: a large forehead, and eyes positioned low on the face. This is why anime, chibi art, and most commercial stuffed animals use:

• Vertical position: eyes at 50-55% down from the top of the head
• Horizontal spacing: eye centres at +/- 20-25% of head width from the midline

Realistic / lifelike style

Adult animal proportions put the eyes higher on the skull, and set the centres further out toward the sides:

• Vertical position: eyes at 40-45% down from the head top
• Horizontal spacing: +/- 30-35% from centre (varies by species)

Why the “cute” eyes look wider apart when the numbers say they are closer

This trips up almost everyone drafting a pattern, and it is worth being clear about because the two styles pull in opposite directions on the same measurement. A chibi face has its eye centres nearer the midline, at 22% of head width rather than 32%. It does not look that way, because chibi eyes are enormous: the eye itself spans most of the gap between the centre line and the cheek, so the visible eyes almost meet in the middle and almost reach the edges. A realistic animal has small eyes whose centres sit much further out toward the temples.

So the ratio is describing the pupil position, not the apparent spacing. If you move the centres out to the realistic 32% and keep the big chibi eyes, you get a face that reads as startled or unwell rather than cute. Match the eye size to the spacing.

The formula

eye_Y = head_height x vertical_ratio eye_X_from_center = head_width x horizontal_ratio

Nose placement (cute style): nose at 65-70% down, centred. Mouth corners at 75% down, +/- 15% from centre. Realistic faces put the nose lower, around 78%, with the mouth at 88%, because the muzzle projects further on an animal than on a chibi.

Eye size, which nobody publishes and everybody guesses

Safety eyes come in fixed sizes: 6, 9, 12, 15, 18, 21, 24 and 30 mm. As a proportion of head width, a cute face wants roughly 9-12% and a realistic one 5-7%. On a 12 cm head that works out at 12.6 mm for chibi and 7.2 mm for realistic, so you reach for the 12 mm and the 6 mm. Erring one size up reads younger and one size down reads older, which is a useful dial once you know where the middle sits.

Safety eyes vs embroidery

Safety eyes (plastic backs with locking washers) are rated for toys for children 3 and older. For under-3 toys, embroider the eyes in yarn. Nothing with a removable part belongs on the face of an infant toy, and a safety eye that pulls through the fabric backing is one of the commonest findings in toy safety testing. Embroidered features have a practical advantage too: you can adjust the position after stuffing, while safety eyes have to go in before the final stuff and are permanent the moment the washer clicks on.
