Acoustic vs Classical Guitar: What's the Real Difference?

Walk into any music store, and you’ll find two types of guitars often lumped together—acoustic guitars and classical guitars. At first glance, they might look strikingly similar: hollow bodies, sound holes, no need for amplifiers. But the moment you pick one up and start playing, you’ll realize they’re worlds apart.

Whether you're a curious beginner or a seasoned guitarist eyeing a new instrument, understanding the differences between acoustic and classical guitars isn’t just helpful—it’s essential. Let’s break it all down and answer once and for all: What’s the real difference between an acoustic and a classical guitar?

1. Strings: Steel vs Nylon – The Heart of the Difference

Let’s start with the most obvious and influential distinction:

• Acoustic guitars use steel strings

• Classical guitars use nylon strings

This isn’t just a cosmetic difference—it changes everything from tone to playability.

Steel Strings (Acoustic Guitar)

Steel strings are tougher, denser, and under higher tension. They produce:

• A bright, crisp, and metallic tone

• Louder volume and better projection

• Greater sustain and resonance

Steel strings are more responsive to strumming and picking, making them ideal for folk, country, rock, pop, and blues.

Nylon Strings (Classical Guitar)

Nylon strings, especially on the treble side, are softer and produce:

• A warm, rounded, and mellow tone

• Less sustain and projection compared to steel

• Easier playability for beginners due to lower tension

These strings suit classical, flamenco, Latin, and fingerstyle music, where tonal warmth and precision are preferred.

🎸 Pro Tip: Switching strings between the two types of guitars is a bad idea. The guitar’s construction is optimized for the string type—changing them can lead to bowed guitar neck or damage the bridge.

2. Neck and Fingerboard: Width, Shape, and Comfort

The neck is where a lot of players start to feel the difference.

Classical Guitar Necks:

• Wider necks (usually 2 inches at the nut)

• Flat fingerboards

• No fretboard markers (dots) on the front—only small side markers

This wider spacing is ideal for:

• Precise fingerstyle playing

• Complex chord voicings

• Avoiding unintentional string contact

However, for players with small hands or those used to steel-string acoustics, the neck can feel bulky.

Acoustic Guitar Necks:

• Narrower necks (about 1.7 inches at the nut)

• Often feature a slight radius on the fingerboard for easier barre chords

• Front-facing fret markers

This makes steel-string acoustics better suited for chord-heavy music, strumming, and playing with a pick.

3. Body Shape and Size

The shape and size of the guitar body affect tone, projection, and player comfort.

Classical Guitars:

• Smaller, symmetrical bodies with a gentle waist curve

• Typically lighter in weight

• Lack of a pickguard

These are designed for lap positioning—held at an angle with the neck tilted upward, often with a footstool or support.

Acoustic Guitars:

• Come in many shapes: dreadnought, jumbo, concert, auditorium, etc.

• Often larger and heavier than classical guitars

• Usually have a pickguard to protect the body from pick scratches

Larger bodies produce more volume, deeper bass, and longer sustain—ideal for playing in bands or loud settings.

4. Playing Style and Technique

The construction of each guitar influences how it’s played.

Classical Guitars:

• Played primarily using fingerstyle techniques

• Traditional posture with no strap, held between the legs

• Great for polyphonic music, arpeggios, and solo classical pieces

Because of the string spacing and tone, they lend themselves beautifully to intricate, melodic playing.

Acoustic Guitars:

• Played with a pick or fingers

• Often played while standing, using a strap

• Best for strumming chords, flatpicking, and sing-alongs

They're the go-to instrument for singer-songwriters, thanks to their ability to blend rhythm and harmony seamlessly.

5. Sound and Tone

The tonal difference between acoustic and classical guitars is one of the most important distinctions.

While subjective, most players agree that nylon strings deliver a more emotive, expressive sound, while steel strings cut through better in a mix.

6. Construction and Bracing

Internally, the bracing patterns differ significantly.

Classical Guitars:

• Use fan bracing—light and spread out

• Designed to support lower tension from nylon strings

• Delicate construction suited to intimate, subtle playing

Acoustic Guitars:

• Use X-bracing—stronger and more rigid

• Built to withstand high tension of steel strings

• More robust for louder dynamics and aggressive play

This internal architecture influences not just durability but also tone projection and responsiveness.

7. Tuning Pegs and Bridge Design

Even the tuning and bridge hardware varies:

Classical Guitar:

• Open-gear tuners with side-facing pegs

• Tie-block bridge: nylon strings are tied at the bridge

Acoustic Guitar:

• Closed-gear tuners with back-facing pegs

• Pin bridge: steel strings have ball-ends secured by bridge pins

This may seem minor, but it reflects the overall construction philosophy: delicate and refined vs. rugged and loud.

8. Price and Availability

You’ll find entry-level models for both types, but:

• Classical guitars are often cheaper at beginner levels due to simpler construction and materials

• Acoustic guitars vary widely in price due to wood choice, body size, electronics, and brand

At the higher end, both can be extremely expensive, especially handmade or luthier-built instruments.

9. Use of Electronics and Pickups

Modern acoustic guitars often come electrified:

• Acoustic-electric guitars have built-in pickups and preamps for amplification

• Great for gigging, busking, and live performances

While some classical guitars have pickups too, they’re less common and usually used in professional flamenco or fusion setups.

10. Music Genres and Artists

Finally, your choice may come down to the type of music you want to play.

Famous Classical Guitarists:

• Andrés Segovia

• Julian Bream

Famous Acoustic Guitarists:

• James Taylor

• Ed Sheeran

• Tommy Emmanuel

Each group has defined their genre using the distinct tonal qualities of their chosen guitar.

So Which One Should You Choose?

Here’s a quick guide depending on your needs:

There’s no right or wrong here—just the right guitar for your goals.

Final Thoughts: Not Just a Matter of Strings

The difference between acoustic and classical guitars goes far beyond just the strings. It’s about how the instrument responds to touch, what kind of sound it produces, and how it fits into your musical journey.

If you're looking for a warm, elegant sound and fingerstyle accuracy, the classical guitar may be your perfect companion. If you prefer versatility, volume, and modern playability, then the acoustic guitar is your stage mate.

In the end, it all comes down to the sound that speaks to you.

🎸 FAQ: Acoustic vs Classical Guitar

Q1. Can you use a pick on a classical guitar?
Yes, but it’s not recommended. The soft nylon strings and delicate top can get easily damaged by picks.

Q2. Is it easier to learn guitar on a classical guitar?
Many beginners find classical guitars easier due to softer strings and less tension, though the wide neck can be a challenge.

Q3. Can I play pop or rock on a classical guitar?
Technically, yes—but the tone may not match the genre’s bright, punchy style.

Q4. Can I change nylon strings on an acoustic guitar?
No—acoustic guitars are built for high-tension steel strings. Nylon strings won’t work properly and may even affect soundboard tension.

Q5. What’s better for children—acoustic or classical?
Classical guitars are often better for young learners due to their smaller size and gentle strings.
