Choosing the right dowel width is one of the most overlooked decisions in macrame — yet it directly affects how straight your piece hangs, how many cords you can attach, and how the finished work feels on the wall. The general rule is to match dowel diameter to project width and cord thickness: thin dowels for small delicate pieces, thick dowels for large wall hangings and room dividers. This guide maps specific diameter ranges to specific project types so you can pick the right size before you buy.

Why Dowel Width Matters
A dowel that is too thin for its project will bow under the weight of the cord, making your finished piece hang crooked. A dowel that is too thick for a small project looks clunky and overwhelms the work. Getting the match right means your piece hangs cleanly from day one without any adjustments.
There are three things that determine the right dowel width:
- Project width — wider pieces need stiffer, thicker dowels
- Cord thickness — heavier cord adds more weight and creates more downward pull
- Number of strands — more strands = more lateral crowding and more weight
All three work together. A narrow wall hanging made with 20 strands of 2mm cord is a very different load from a 1-metre wide curtain panel made with 80 strands of 5mm cord.
Dowel Diameter Guide by Project Type
Small Projects: 6mm to 10mm Diameter
This range covers most small decorative pieces: mini wall hangings under 40cm wide, macrame bookmarks, small keychains, and decorative frames.
At this scale, you are typically working with 2mm or 3mm cord and attaching fewer than 30 strands. The dowel does not carry much weight, so a 6mm to 10mm diameter provides plenty of rigidity.
Best for: Mini wall hangings, keychains, small frames, craft fair samples
A 10mm dowel is a good default for this category. It looks proportionate to small pieces without being visually heavy.
Medium Projects: 12mm to 18mm Diameter
This is the most common range for standard wall hangings between 40cm and 80cm wide. Most beginner tutorial projects — including basic plant hanger hangers and medium-sized wall art — fall here.
At this scale, you are often working with 4mm cord and attaching 30 to 60 strands. The 12-inch wooden dowels from Bochiknot — use code KNOT10 for 10% off — fit squarely in this category. They are well-proportioned for the wall hangings most makers tackle in their first year.
Best for: Standard wall hangings, moderate plant hanger frames, learner projects
A 15mm to 18mm dowel is a reliable choice when you are unsure. It has enough stiffness to handle 4mm or 5mm cord without any risk of bowing.
Large Projects: 20mm to 30mm+ Diameter
Large wall hangings over 80cm wide, curtain panels, macrame room dividers, and statement pieces need a thicker dowel. Once you are attaching 60 or more strands — especially with heavy 5mm cord — a thin dowel will flex noticeably.
At this scale, some makers switch to wooden curtain rods or hardwood dowels rather than standard craft dowels, because they offer more structural rigidity over long spans.
Best for: Statement wall art, curtain panels, room dividers, large commissioned pieces
If your piece is wider than 100cm, consider using two shorter dowels end to end, or sourcing a hardwood option rated for the load.
Matching Dowel Diameter to Cord Thickness
Project width is only half the equation. Cord weight matters too.
| Cord Thickness | Recommended Dowel Diameter |
|---|---|
| 1.5mm – 2mm | 6mm – 10mm |
| 3mm – 4mm | 10mm – 18mm |
| 5mm | 15mm – 25mm |
| 6mm+ (chunky) | 20mm+ |
Thicker cord is heavier and takes up more horizontal space on the dowel. If you are working with chunky 5mm or 6mm cord, size up your dowel even for smaller projects.

Wood Type and Grain
Most craft dowels are made from birch or pine — both are light, smooth, and affordable. For pieces that will carry a lot of weight (like a room divider), a hardwood dowel such as oak or beech holds up better over time.
Things to check when buying:
- Straightness — place the dowel on a flat surface and roll it gently. Any wobble means it is warped and will hang crooked.
- Surface smoothness — rough grain can snag fine cord. Sand lightly with 220-grit paper if needed.
- Knot-free sections — wood knots create weak spots. For structural pieces, choose sections with straight, even grain.
The macrame measuring tape is useful here — measure your dowel diameter accurately before cutting to length so your hanging cord sits at the right height.
Dowel Length vs. Dowel Diameter
These are two separate decisions that new makers sometimes confuse.
Diameter is what we have been discussing — the thickness of the dowel, which determines stiffness and weight capacity.
Length determines how wide your finished piece can be. Standard craft dowels come in common lengths (30cm, 60cm, 90cm). As a rule, your dowel should be a few centimetres longer than your planned project width to allow room for the hanging cord loops at each end.
You can always cut a longer dowel down to size. You cannot make a short dowel longer.
Alternatives to Round Dowels
Round wooden dowels are the most common mounting option, but they are not the only one. Consider these alternatives:
- Wooden branches — foraged or purchased driftwood adds an organic feel. Sizing is less precise; aim for roughly the same diameter guidelines above.
- Metal rings and rings frames — great for circular macrame pieces. Sizing is diameter of the ring, not a length decision.
- Copper pipes or rods — clean modern aesthetic, very rigid, excellent for large installations.
- Wooden hoops — popular for dream catchers and circular wall hangings.
Each of these alternatives follows the same logic: match the structural strength to the scale and weight of the piece.
Common Dowel Mistakes
Using a too-thin dowel for heavy 5mm cord. This is the most frequent error. The bowing may not be visible at first but becomes obvious once the piece hangs on a wall for a few weeks.
Cutting the dowel too short. Always leave at least 3–5cm on each side beyond your project width for the hanging cord. If you cut flush to the project width, the lark’s head knots at the edges have nowhere to go.
Skipping the straightness check. A warped dowel makes your whole piece hang at an angle. Check before you start knotting, not after.
