Buyer's guide
Point size and ink type
The number on the barrel is the width of the ball at the tip. A 0.38 or 0.4 point draws a thin line for small handwriting, math homework and planner boxes, and fans of needle points such as The Pen Addict prize that precision, but it can feel scratchy and the line looks lighter. A 0.5 point is the middle ground most planner fans settle on. A 0.7 point, the common default in the United States, lays down more ink, so it feels smoother and looks darker but takes longer to dry. A 1.0 point is bold enough for signatures and cards.
Ink matters too. Classic gel ink is thick and colorful. Pentel's liquid gel is thinner, so it flows more like a rollerball and dries faster. Pigment inks, such as Uni's, grab the paper fibers and hold up against water and fading, which matters for checks and documents. Opaque inks, like Sakura's pastels and metallics, sit on top of the page so they show on black paper.
Smudging, drying time and left-handed writers
Gel ink sits wet on the page for a few seconds, so anyone whose hand trails across fresh writing, especially left-handers, should put drying speed first. A finer point and a fast-drying ink help the most. In a two-month comparison of 19 pens, Your Best Digs timed smudging and found Pentel's liquid gel and Zebra's quick-dry ink among the fastest, while thick, opaque inks and some 0.7 points smeared badly. Zebra's Sarasa Dry, a lefty favorite, is sold in the U.S. mostly as a Japanese import, so check the seller before you buy.
Paper changes things as well. Smooth, coated paper keeps ink on the surface longer, so it dries slower, while cheap copy paper soaks it up faster but can let bold ink feather or show through. If your gel pens bleed through a notebook, try a finer point before switching brands. For the smoothest pens for writing long pages, some people move up to a fountain pen; see our guide to the best fountain pens.
Refills, pack sizes and what you pay per pen
Most gel pens are sold in packs, so compare the price per pen rather than the sticker. A four-pack and a 12-pack of the same pen can differ a lot per pen, and bulk boxes make sense for classrooms and shared desks where pens go missing. Assorted color packs often cost more per pen than black-only boxes.
Refillable models, such as the Pilot G2, Pentel EnerGel and Zebra's steel pens, take cartridges that cost less than a new pen and cut waste. Check that you're buying the matching refill: Pilot, Pentel and Zebra each use their own sizes, and retailer guides such as JetPens' EnerGel guide list which refill fits which barrel. A refill also lets you keep a barrel you like and swap point sizes or colors.
If you sketch or take math notes that need erasing, a pencil may suit you better; we compare options in our best mechanical pencils guide. Shopping for someone else? A color set or a steel pen makes an easy add-on to our gifts for writers.
How we researched this
We compared nearly 20 gel pen packs from Pilot, Pentel, Uni, Zebra, Paper Mate, BIC, Sharpie and Sakura. We read a two-month hands-on comparison, a forum shootout, single-pen reviews from The Gentleman Stationer and The Pen Addict, and maker and retailer guides, then checked each Amazon listing on Oct. 23 for price, stock, pack size, point size and refills. Imports, giant mixed bundles and near-copies of another pick were left out, and smudging complaints weighed heavily.

Frequently asked questions
What is the best gel pen for everyday writing?
For most people, the Pilot G2 is the safe choice: it's sold almost everywhere, writes a dark, smooth line and takes refills. If you smudge your writing or write left-handed, the Pentel EnerGel RTX dries faster. For small handwriting, a 0.38 or 0.5 point such as the Uni-ball 207 Ultra Micro keeps letters crisp.
Which gel pens are best for left-handed writers?
Look for quick-drying ink and a finer point. Pentel's EnerGel liquid gel is the easiest lefty-friendly option to find in the U.S., and Zebra's Sarasa Dry is another favorite, though it's often sold as an import. Thick 0.7 or 1.0 points and opaque or pastel inks take longer to dry and smear more.
What's the difference between 0.38, 0.5 and 0.7 mm gel pens?
The number is the size of the ball at the tip, which sets the width of the line. A 0.38 point writes a thin, precise line but can feel scratchy. A 0.5 point is a balanced middle. A 0.7 point writes a bolder, smoother line that looks darker and takes a little longer to dry.
Are gel pens better than ballpoint pens?
Gel pens write darker, more colorful lines with less pressure, which helps on long notes and with hand fatigue. Ballpoints use oily ink that dries almost instantly, lasts longer per pen and rarely smears or bleeds. If you write fast or on cheap paper, a quick-drying gel or a liquid gel pen splits the difference.
Do gel pens bleed through paper?
They can, especially bold 0.7 and 1.0 points on thin notebook or copy paper. Finer points lay down less ink and bleed less. Pigment-based inks tend to stay put better than wetter dye inks. If a pen shows through your pages, try a finer point or heavier paper before giving up on the brand.
Can you refill gel pens?
Many popular ones take refills, including the Pilot G2, Pentel EnerGel and Zebra's steel pens. Refills cost less than a new pen and let you keep a barrel you like. Each brand uses its own refill size, so match the brand, model and point size when you order. Most bright color sets aren't refillable.
