Our verdict
There is no single winner: choose round drills for your first kit, relaxed sessions, and photo-like or organic artwork, and square drills when you want a seamless, mosaic-like finish and crisp detail on geometric or highly detailed designs.

A large square-drill canvas that shows off the gap-free, mosaic finish square drills are known for.
Check price on AmazonEvery diamond painting kit asks you the same question before you even open the box: round drills or square drills? The “drills” are the small faceted resin gems you place on the adhesive canvas — nothing is actually drilled. Round drills are circles, about 2.8 mm across; square drills are tiles, about 2.5 mm across, that fit edge to edge like a mosaic. Both use the same DMC colour codes and the same basic tools, but they change how the work feels, how fast it goes, and how the finished piece looks up close.
This guide compares the two drill types on the things that actually decide a purchase — coverage, speed, difficulty, finished look, and which artwork suits each — and then shows one real, verified example kit for each type. It is based on aggregated verified buyer reviews and published spec comparisons, not hands-on testing: we have not personally completed these kits, and no result here is a guarantee of how your project will turn out. Star ratings shown on this page are our editorial scores informed by that aggregated buyer feedback.
Coverage: square wins, round hides its gaps well
Square drills tile perfectly, so the finished canvas is essentially gap-free — no printed canvas shows between drills, and the surface reads as one continuous mosaic. Round drills cannot tile perfectly, so small gaps remain between circles and roughly 5% of the canvas can peek through. Up close that gives round-drill work a slightly textured, pointillist look; from a normal viewing distance of a few feet, most viewers barely notice it. If a flawless, wall-ready surface matters most to you, square drills have the clear edge. If you will view the piece from across a room, the gap question matters far less than the design itself.
Speed and difficulty: round is the forgiving start
Round drills have no orientation — a circle sits correctly however it lands — so you pick up, place, and move on without rotating each gem. Small placement slips vanish into the gaps between neighbours. Square drills must sit straight and flush against their neighbours, or a crooked drill shows immediately and can push a whole row out of line. Experienced crafters often use a checkerboard method on large single-colour square areas — placing every other drill first, then filling the gaps — to keep rows straight. The practical result: a round-drill canvas of the same size usually takes less time and less concentration than its square-drill equivalent, which is why round is the standard recommendation for a first kit.
Finished look: soft sparkle versus crisp mosaic
Round drills give a softer, more glittery finish that many crafters compare to sparkly cross-stitch. Their faceted tops catch light from many angles, and the look suits organic subjects — landscapes, animals, and photos — where flowing shapes hide the gaps. Square drills give a flatter, sharper, mosaic-like finish with visible grid lines between tiles up close and smoother colour transitions at a distance. They suit geometric designs, mandalas, pixel-style art, and highly detailed images where clean edges matter. One honest catch the top guides agree on: neither finish is objectively “better” — the right choice follows the artwork, not a universal ranking.
The buyer-complaint pattern most guides gloss over
The most common frustration reported for square drills is not difficulty in the abstract — it is drills that pop out of place or rows that drift when one drill is slightly off-size or off-angle, forcing rework on a section. The most common frustration for round drills is the opposite: buyers who expected full coverage are disappointed by visible gaps or canvas showing through, especially on dark backgrounds. Knowing which complaint would bother you more is a surprisingly reliable tiebreaker. If uneven rows would frustrate you, start round. If visible gaps would frustrate you, go square and budget extra patience.
How to choose in 30 seconds
Choose round drills if you are buying your first kit, want a relaxing project, like sparkly finishes, or are working from a photo or organic design. Choose square drills if you have finished at least one kit, want a seamless mosaic finish, love geometric or highly detailed art, and enjoy precise, methodical work. Size matters too: start under about 40 cm on your longest side for a first project either way, and save large canvases for your second or third kit, when you already know which drill rhythm you enjoy.

1. TINY FUN 12 Pack Diamond Painting Kits for Adults 5D Diamond Art Kit Paint by Number for Beginners, DIY Paint with Round Full Drill Diamonds Paintings Gem Art for Home Wall Decor Gift (12X16 Inch) — Best for Beginners
This is the round-drill example: twelve 12x16 inch waterproof canvases, each with its own full set of round resin drills, pen, wax, and grooved tray. The listing’s verified Amazon average is 4.7 out of 5 stars across roughly 2,700 ratings, and aggregated buyer feedback praises the clear, high-definition symbols and flat-packed canvases. It is a natural first purchase because twelve smaller projects let you learn the rhythm — and discover whether you even like the hobby — without committing to one large canvas. The repeated buyer complaint to watch for is occasional missing pieces or accessories in a pack, so count drills and tools when a kit arrives rather than mid-project.
- Forgiving round drills: no orientation, fast placement, slips stay hidden
- Twelve canvases and tool sets — good value per project and easy gifting
- Clear symbols and waterproof canvases, per aggregated buyer feedback
- Verified 4.7-star average across roughly 2,700 Amazon ratings
- Small gaps between round drills are part of the finish, not a flaw
- Occasional buyer reports of missing drills or accessories in a pack
- 12x16 inch size limits fine detail compared with larger canvases
2. ARTGOTO Large Square Drill Diamond Art Painting Kits for Adults,15.7x27.5inch/40x70cm Dreamcatcher A DIY Full Square Diamond Dots Large Size,Big Gem Art and Crafts for Home Wall Decor Gifts — Best Square-Drill Example
This is the square-drill example: a large 15.7x27.5 inch (40x70 cm) Dreamcatcher canvas with full square drills and two complete tool sets, so two crafters can work or you always have a spare pen. The larger canvas is exactly where square drills earn their reputation — the Dreamcatcher geometry and fine lines stay crisp in a way a small square canvas cannot show, and the gap-free mosaic finish is the point of the purchase. Treat it as a second-kit step up rather than a first project: the size plus the alignment demands make it a longer, more deliberate build, and straightening rows every few lines with a ruler or straightener tool is part of the routine, not a sign you are doing it wrong.
- Gap-free, mosaic-like finish with crisp detail on a large canvas
- Two full tool sets included — share the project or keep a spare
- Large 40x70 cm size suits detailed, display-worthy artwork
- Square drills give a satisfying snap-fit as rows fill in
- Demands precise, straight alignment — crooked drills show immediately
- Slower than an equivalent round-drill canvas, especially for beginners
- Large size needs a proper workspace and longer commitment
The verdict, restated
Round drills suit first-time crafters, relaxed sessions, and photo-like or organic artwork; square drills suit detail lovers, geometric designs, and anyone chasing a seamless mosaic finish. If you are still unsure, buy round first — it is the cheaper mistake to make, since you will finish faster and learn whether you enjoy the craft, and you can always choose square for your second canvas once you know your rhythm. Either way, check the drill shape in the listing title and photos before ordering, because a canvas made for one shape cannot take the other.

Frequently asked questions
Are round or square drills better for beginners?
Round drills are the easier start. They have no orientation to worry about, so placement is faster and small alignment slips are far less visible. Square drills reward patience and precision instead.
Do square drills really cover the canvas better?
Yes. Square drills sit edge to edge like mosaic tiles, giving essentially full coverage with no printed canvas showing between drills. Round drills leave small gaps, so roughly 5% of the canvas can peek through up close.
Which drill type sparkles more?
Both sparkle, but in different ways. Round drills are widely reported to give a softer, more glittery finish, while square drills give a flatter, crisper, mosaic-like shine. At normal viewing distance the difference is much smaller than it looks up close.
Can I mix round and square drills on one canvas?
No — each canvas is printed for one drill shape and size, so the drills are not interchangeable. Choose the drill type when you buy the kit, not after you start.
Are round drills faster to place than square drills?
Generally yes. Because round drills need no rotation or exact alignment, most crafters finish a round-drill canvas faster than the same design in square drills, which demand straight, flush rows.
Which drill type is better for detailed or photo-like designs?
It depends on the design. Square drills suit geometric art, mandalas and crisp detail because their grid stays sharp. Round drills suit photos and organic scenes well because their softer finish hides small gaps and suits flowing shapes.
