Eyeliner Guide: Every Format, Every Technique, Every Eye Shape

This eyeliner guide breaks down every major liner format, the best technique for each, and which eye shape it suits best. If you want sharper wings, softer definition, or a style that actually flatters your eyes, start here.

In this eyeliner guide, you’ll learn how pencil, liquid, gel, kohl, and kajal behave on the skin, plus how to match them to almond, round, hooded, downturned, and monolid eyes. The goal is simple: make liner feel easier and help you choose the right look faster.

Eyeliner Guide: Every Format and What It Does

There is no single “best” eyeliner. The right one depends on how precise you want the line to be, how much time you have, and where you plan to apply it. 
As celebrity makeup artist Lisa Eldridge has said in interviews, the best makeup tools are the ones that suit the look you want and the shape you are working with.

Pencil Liner

What it is: Soft, forgiving, and easy to blend. Pencil liner is usually the easiest place to start if you are new to makeup.

Best for: Beginners, smudged liner, tightlining, and the waterline.

Why it works: Pencil gives you control without needing a perfectly steady hand. It is less sharp than liquid liner, but that softness is useful when you want a lived-in or smoky finish.

Limits: It is not the best choice for a crisp graphic liner or a super sharp cat eye. It can also transfer more than gel or liquid.

How to use it:

• Work in short strokes instead of one long line.
• Connect the strokes along the lash line.
• Smudge right away with a small brush or your fingertip if you want a softer look.
• Leave it as-is for light definition.

Best placement tip: Pencil is ideal for the waterline and tightlining, which means filling the space between the lashes. That makes lashes look fuller without adding a heavy visible line.

Liquid Liner

What it is: The most precise eyeliner format. Liquid liner creates clean edges and a bold finish.

Best for: Cat eyes, graphic liner, sharp definition, and long-wear looks.

Why it works: Liquid liner is made for drama and precision. Waterproof formulas usually hold up best and can last 6 to 8 hours or more, depending on skin type, humidity, and rubbing.

Limits: It is less forgiving than pencil or gel. If the line goes wrong, you usually need to remove and redo it. It also is not suitable for the waterline.

Tip applicator guide:

• Felt tip: Stiffer, easier to control, and often friendlier for beginners.
• Brush tip: More flexible and better for very fine lines.

How to use it:

• Rest your elbow on a flat surface.
• Look straight ahead into a mirror instead of looking down.
• Build the line in small connected strokes.
• Finish the flick last so you can adjust the angle.

Quick tip: A slightly thinner line usually looks more natural in daytime makeup, while a fuller line gives a strong

Gel Liner

What it is: A creamy liner that is usually applied with an angled brush or thin liner brush.

Best for: Upper lash lines, smoky definition, and styles that need both control and softness.

Why it works: Gel liner sits between pencil and liquid. It gives more precision than pencil but feels easier to work with than liquid for many people. It is also very blendable while wet and usually sets to a firmer finish within about 60 seconds.

Limits: The main mistake is using too much product. That can make the line messy and harder to control.

How to use it:

• Pick up only a small amount of product.
• Apply close to the lash line.
• Build the line with short, connected strokes.
• Use a thinner brush for detail and a wider angled brush for a bolder look.

Why people like it: Gel is a strong everyday option if you want the flexibility of a smudged look but still want enough definition for a polished finish.

Kohl and Kajal

What they are: Very soft, deeply blendable liners with a long history in South Asian, Indian, and Middle Eastern beauty traditions.

Best for: Waterline definition, smoky eyes, and soft rimmed looks.

Why they work: Kohl and kajal are made for a diffused effect. They are especially useful when you want the eyes to look more shaded and sultry instead of sharply lined.

Limits: Some traditional formulas have included lead compounds in certain markets. Choose modern, lead-free formulas and check labels carefully.

How to use them:

• Apply lightly to the waterline for instant depth.
• Smudge along the lash line for a smoky base.
• Pair with pencil or gel if you want a more controlled shape.

Good to know: If you have sensitive eyes, test any waterline product first and avoid sharing makeup to reduce irritation risk.

Eyeliner Guide: Which Eye Shape Suits Each Style

The best eyeliner shape depends on the eye shape you are working with. Small changes in angle, thickness, and placement can make a big difference. If you are unsure of your eye shape, use your own mirror test or try a trusted eye shape guide before choosing a style.

Almond Eyes

Almond eyes are balanced, with visible upper and lower lash lines and a moderate lid. This shape is versatile, so most eyeliner styles work well.

Best styles:

• Classic thin liner along the upper lash line
• Cat-eye flick that extends upward and outward
• Tightlining for soft definition

Why it suits this shape: Almond eyes already have a naturally lifted look, so you can keep the liner simple or build into something more dramatic without fighting the eye shape.

Round Eyes

Round eyes show more of the iris and tend to look open and bright. The goal with eyeliner is usually to add length, not more roundness.

Best styles:

• Stretch liner beyond the outer corner with a horizontal flick
• Keep the colour heavier on the outer third of the upper lash line
• Use a thin line on the inner corner

Avoid: Thick liner all the way around the eye, especially on the lower lash line, because it can make the eye look smaller and rounder.

Best format match: Pencil or gel often works well here because you can build the outer third slowly and blend if needed.

The right eyeliner doesn’t just draw a line—it teaches the eye how to be seen.

Hooded Eyes

Hooded eyes have a fold of skin that partly covers the upper lid when the eyes are open. This means liner placed too low can disappear.

Best styles:

• Draw liner with your eyes open so you can see the final shape.
• Place the line slightly above the hood so it stays visible.
• Keep the inner corner thin and increase thickness toward the outer corner.

The test: Apply liner, then open your eyes and look straight into the mirror. If the liner vanishes, raise it by 1 to 2 mm and check again.

Best format match: Liquid can work well for a lifted wing, but gel is often easier if you want to control the thickness before it sets.

Downturned Eyes

Downturned eyes have outer corners that sit lower than the inner corners. The aim is to create a subtle lifted effect.

Best styles:

• Angle the flick upward at the outer corner
• Keep the liner thin through the inner two-thirds
• Build a little more thickness at the outer third

Avoid: Following the natural downward angle with the liner, because that can make the eye look more drooped.

Best format match: Liquid gives the cleanest lifted wing, while pencil can help you sketch the shape first before committing.

Monolid Eyes

Monolid eyes do not show a visible crease. That gives you a smooth lid surface that can hold bold liner beautifully.

Best styles:

• Thicker upper lash line with a gradual increase toward the outer corner
• Graphic liner and coloured liner styles
• Lower lash line liner in a matching or complementary shade

Why it suits this shape: Monolid eyes can carry strong shapes well because the full lid is visible. A slightly thicker liner often shows better than a tiny thin line.

Best format match: Gel and liquid are both strong choices, depending on whether you want soft control or a sharper finish.

Eyeliner Guide: The Cat-Eye Technique for Every Format

The cat-eye is one of the most requested eyeliner looks in beauty. The steps stay similar across formats, but the tools change how fast and how sharp the result feels.

The dot method

This method works with pencil, gel, or liquid. It helps you map the shape before you commit.

1. Place a small dot where you want the flick to end.
2. Place a second dot on the lash line near the inner corner.
3. Connect the outer dot back toward the lash line to outline the flick.
4. Fill in the triangle between the lines.
5. Finish the upper lash line by joining the inner corner to the base of the flick.

Why this helps: Breaking the shape into steps makes the cat-eye easier to control, especially if you have hooded or downturned eyes.

The tape method

This method is best with liquid liner when you want a very crisp edge.

1. Place a small piece of tape from the outer corner at the angle of your desired flick.
2. Use the tape as a guide while applying the liner.
3. Remove the tape before the liner fully dries.

Why this helps: The tape creates a cleaner edge and can reduce uneven flicks, especially when you are learning.

Most common cat-eye mistake: Drawing the flick downward. The flick should extend from the end of the lash line and angle upward, even if only slightly.

Quick Eyeliner Tips That Make a Big Difference

• Use less product first. It is easier to build liner than to fix a thick line.
• Match the format to the job. Pencil for softness, liquid for sharpness, gel for balance, and kohl or kajal for smoke.
• Look straight ahead while lining. That helps you see the true shape on hooded or deep-set eyes.
• Start thin. You can always deepen the line later.
• Keep the outer corner light if your eyes turn down. That gives a lifting effect.
  
  For downturned eyes, keep the line thinner as it approaches the outer corner and avoid dragging the wing too far downward. A slightly lifted flick creates a brighter, more open look and helps balance the eye shape.
  
  

FAQ: Eyeliner Guide Questions

What eyeliner format is easiest for beginners?

Pencil liner is usually the easiest because it is soft, forgiving, and simple to blend if you make a mistake.

Which eyeliner lasts the longest?

Waterproof liquid liner often lasts the longest and gives the most defined finish. Gel can also wear well, depending on the formula and your skin type.

Can I use liquid liner on the waterline?

No. Liquid liner is not made for the waterline. Use pencil, kohl, or kajal products that are designed for that area instead.

What liner is best for hooded eyes?

Many people with hooded eyes prefer gel or liquid applied with eyes open, because the line stays more visible. The key is placement, not just product choice.

How do I make a cat eye look even?

Use the dot method or tape method, keep your elbow steady, and check both eyes with your face relaxed and looking straight ahead.
