Quick answer
To sign 'dad' (or 'father') in ASL, spread your fingers into an open 5 handshape and tap the side of your thumb against your forehead. The high forehead location marks male family signs, which is how 'dad' differs from 'mom,' signed at the chin.
How to Sign Dad in Sign Language
“Dad” — also signed as “father” — is one of the first family signs many people learn in American Sign Language (ASL). To make it, spread your fingers into an open 5 handshape and tap the side of your thumb against your forehead a couple of times. The high forehead location is the key: it marks “dad” as a male family member.
This placement is part of a tidy ASL pattern. Male relatives sit high near the forehead, and female relatives sit low near the chin, which is exactly how “dad” and “mom” stay distinct.
Step-by-Step: Signing Dad
| Step | What to Do |
|---|---|
| 1. Handshape | Open your hand into a 5 shape, fingers spread. |
| 2. Palm orientation | Turn your palm to the side, facing across. |
| 3. Location | Bring the side of your thumb to your forehead. |
| 4. Movement | Tap the forehead a couple of times. |
| 5. Keep it relaxed | The fingers stay spread and loose. |
A relaxed open hand with the thumb tapping the forehead reads clearly as “dad.”
Dad vs. Mom: The Same Hand, Different Spot
These two signs share a handshape but differ by location, which is the whole trick to telling them apart.
| Sign | Handshape & Location | Meaning |
|---|---|---|
| Dad | Open 5 hand, thumb taps the forehead | Father (male, high) |
| Mom | Open 5 hand, thumb taps the chin | Mother (female, low) |
High equals male, low equals female — a rule that carries across many ASL family signs.
Common Mistakes to Avoid
- Tapping the chin instead of the forehead. Forehead is “dad”; chin is “mom.”
- Using a fist or a pointing finger. The handshape is an open, spread 5.
- Tapping with the fingertips. It is the side of the thumb that touches the forehead.
- Touching only once. A small double tap reads more clearly.
Family Signs Built on the Same Pattern
ASL organizes many relatives by gender and generation using this high-low rule.
| Sign | Location | Family Member |
|---|---|---|
| Dad | Forehead | Father |
| Mom | Chin | Mother |
| Grandpa | Forehead, then arc forward | Grandfather |
| Grandma | Chin, then arc forward | Grandmother |
Related Signs to Learn Next
“Dad” pairs naturally with these core family and home signs:
- MOM — open 5 hand, thumb tapping the chin.
- FAMILY — two F handshapes circling outward into a group.
- BABY — cradle and rock your arms.
- LOVE — cross both fists over your chest.
- HOME — flattened-O hand touching the cheek twice.
Because family is one of the first things children and new signers want to talk about, “dad” is a high-value early sign for families using baby sign language and for anyone building a practical ASL vocabulary.
Frequently Asked Questions

Open your hand into a 5 handshape with fingers spread, then tap the side of your thumb against your forehead a couple of times. The forehead placement signals a male family member, making this the ASL sign for 'dad' or 'father.'
What is the difference between 'dad' and 'mom' in sign language?
Both use the same open 5 handshape with the thumb touching the face. 'Dad' taps the thumb on the forehead, while 'mom' taps the thumb on the chin. The high-versus-low placement is the ASL pattern that separates male from female family signs.
Is 'dad' a good sign to teach a baby?
Yes. 'Dad' is a meaningful, motivating early sign because it names a beloved person. Babies often approximate it by tapping the forehead with an open hand. Pairing it with 'mom' gives a child two of the most important words in their world.
Why is the 'dad' sign made at the forehead?
ASL groups family signs by gender using location. Male relatives — dad, grandpa, son, brother, uncle — are signed in the upper area near the forehead, while female relatives are signed lower near the chin. The forehead placement marks 'dad' as a male sign.
How do you sign 'father' versus 'dad'?
In ASL, 'dad' and 'father' use the same sign: an open 5 handshape tapping the thumb on the forehead. There is no separate formal sign for 'father.' Tone, context, and facial expression convey whether you mean the casual 'dad' or the formal 'father.'
