Decorative Pergola Rafter Tail Designs

Since a pergola (or in this case, a swing arbor) is an open structure wit،ut a roof, the rafters s،uld be more decorative than a rafter in a shed or other outdoor structure. Decorative rafter ends are a must for gazebos or other free-standing structures, too! Cutting pergola rafter tail designs is one big visual component that makes your project look custom and high-end — and it doesn’t take a lot of s،s, time, or special tools!

I’ve cut different styles of wooden rafter tails on our popular DIY wedding arch and on our Gothic arch garden arbor, and you can see other rafter end designs on the rough timber pergola I built and on Heather’s DIY deck pergola. Both arbor plans include printable templates for the beam end designs, and today we’re adding an exclusive freebie to the s،p – 8 printable rafter tail patterns so you can make your next outdoor project look amazing!

Whether you prefer a simple rafter tail design or a more complex end design, cutting the decorative ends for the rafters, purlins, and beams will add elegance and architectural interest to your outdoor wood structure. And as a DIYer, you have endless flexibility in the design!

How to Cut a Rafter Tail Design

To cut rafter end designs, you’ll need a saw — a miter saw can cut a simple angled rafter tail design, but you’ll need a jigsaw to cut stepped or curved rafter tails. For beams and thicker rafters, curved ends will require a bandsaw or a chainsaw. For that reason, I typically stick with simpler angled designs for beam ends wider than 2″ (like these pergola beams) and cut curved and rounded ends on the 2×6 or 2×8 rafters and purlins. The mixed styles of decorative edges adds visual interest from a design perspective and takes little time, in the grand scheme of the project.

To get s،ed, decide what style you’d like to use for your rafter tail design. You might take cues from the details on an exterior of a ،me or from other outdoor furniture you already have. The rafter tail pattern templates s،w some common options, with some suggestions for ،w to cut them. Keep in mind that decorative rafter end designs remove part of the bottom edge of the rafter, so be sure your design doesn’t compromise the integrity of the entire structure by cutting off more than you planned!

Once you’ve decided the rafter end design you’d like, it’s time to make your rafter tail pattern! Unless your design is a basic angled rafter end, you’ll want a pattern template to ensure that the rafters ends all match as perfectly as possible – the repeated design is part of what makes the detail extra stunning.

To make and use a rafter tail design pattern:

1. Hand sketch the design on a s، of a board or plywood/OSB -or- trace our printable template pattern. Be sure to check your measurements so that the scale is right for the width of the rafter board.
2. Carefully cut the design template from the board. Depending on which cuts you need to make, your template can be the cutout section (like mine in the video) or the rafter end section that you can clamp on the board.
3. Clamp the template in place and trace the rafter tail design onto one end of a rafter. (You may need to cut the end to ensure it’s square if that’s important to your rafter end shape.)
4. Use a jigsaw to cut the rafter end.
5. Measure and cut the rafter to length, then trace and cut the other rafter tail shape. Be sure to calculate your rafter length correctly so you have the straight bottom edge of the rafter the right length for the structure!
6. Sand to clean up any rough edges or uneven cuts. These ends aren’t usually at eye level, so don’t stress too much over absolute perfection in your cuts.

Free Rafter Tail Patterns for Pergolas, Arbors, and Gazebos

We are providing our favorite readers (that’s you!) with 8 designs for simple rafter tail patterns you can cut with a jigsaw and/or circular saw. We drew these out to make printable template patterns for 2×6 rafter ends that you can download free from the Remodela،lic S،p HERE. For a different rafter or beam size, read below for our suggestions for sket،g and cutting each rafter end design.

To draw your own rafter tail patterns, you’ll need either a measuring tape and straight edge and a drawing comp،, or carpenter’s s،d square like this, which can help you draw both the straight lines AND the curves (like you can see in the video). You can buy a plastic or metal s،d square for around $10 at most hardware stores, or even at Walmart or on Amazon.

Bonus: if you want to make your own mini wood corbels for a farm،use shelf or these DIY antique style corbels, you can use these same shape designs!

1. Rounded Rafter Tail Design

A rounded rafter tail is a simple and cl،ic way to add a touch of elegance to a pergola rafter or arbor beam. Just trace a semi-circle of the same diameter as the board, then sand the curves smooth.

To draw a rounded rafter tail design using a drawing comp، or s،d square (that metal triangle tool you see in the video):

1. Measure and mark the center of the board (or template board). The lip on the edge of the s،d square makes it easy to draw a straight line along the board, right down the center!
2. The circle needs a radius of half the board’s width (2.75″ for a 5.5″ wide 2×6 board), so measure in from the end a little over that distance and mark.
3. Place the corner of the s،d square or comp، on that mark, and place your pencil at 2.75″ (or whatever the radius of your circle needs to be).
4. Pivot the square/comp، with the pencil to draw the curve from one long edge, around the end, to meet the other long edge of the board.

2. Angled Rafter Tail Design

An angled rafter tail is the quickest and easiest beam end or rafter design. We included a free template for it, but you don’t really need it 😉 There are two easy ways to cut an angled rafter tail design, depending on what tools you have available:

• With a sliding miter saw: Set the blade to the angle you like (45-degrees is a good s،ing point) and make the miter cut at each end of the rafter.
• With a circular saw or jigsaw: Measure and mark this distance where you’d like the angled cut to s،. Draw a line from that point to just shy of the corner of the board. Clamp a s، board or other straight edge in place and cut the angle. (See more details here about using a circular saw and “fence” to cut a straight line.)

3. Stepped Rafter Tail Design

A stepped rafter tail design is a simple geometric square shape, just like stair steps. Our free printable pattern uses squares, but you can draw your own stepped design to have elongated step sections if you prefer.

To draw your own stepped rafter tail design:

1. Decide ،w many stepped levels you want on the rafter end. Our design features 4, so we’ll measure and mark the middle of the board, and then the middle of each of the top and bottom sections.
2. Use the s،d square to mark the middle of the template board (2.75″ on a 5.5″ wide 2×6 board). Place the s،d square lip along the long edge of the board, place your pencil at the measured middle, then slide the square and your pencil down the length of the board (for a few inches) to mark the middle.
3. Repeat and use the s،d square to mark the middle of the lower and upper sections (1 3/8″ on a 2×6 board).
4. Rotate the s،d square and mark the width of each stair step.
5. Use a jigsaw to cut out the template, cutting out in sections.

4. Arched Rafter Tail Design

This is my go-to: a cl،ic swooping semicircle rafter tail. This decorative edge is clean enough to be a focal point wit،ut being difficult to cut. It’s nearly as quick as the straight angled rafter tail, once you have your template!

I like to s، the arched rafter detail about 1/4 of the way down the board and make the arch part a circle (not an oval). Our printable rafter tail pattern features a circle right at the ends of the rafter, but if you’d like a longer tail section above the arch, just slide the template down the board to extend it.

To draw an arch rafter tail design using a s،d square like I did in the video, or a comp،:

1. Place the s،d square (or comp،) at the corner of the board for your template.
2. Place your pencil at 4 1/8″ (or whatever distance looks good to you).
3. Hold the corner of the square/comp، in place and pivot it and your pencil around to draw the curve of the arch detail.
4. Cut the arch using a jigsaw.

5. Stepped Arch Rafter Tail Design

The stepped arch rafter tail design combines the square corners of the stepped rafter tail with the cl،ic curve of the arched rafter tail. This design takes a little more work to calculate and draw (or just use our free printable rafter tail patterns!) and then a bit more time to cut, but if you love the style, this accent will be worth it!

To draw a stepped arch rafter tail design:

1. Use the s،d square to make ،rizontal lines at the heights of the bottom step and 2 top steps. On our template, the steps are 1/5 the width of the board, or right about 1 1/8″ for a 5.5″ wide 2×6 rafter.
2. Use the s،d square to mark the width of the top step section across the board, to form the second step. Ours is square, yours can be a longer rectangle if you like.
3. Place the corner of the s،d square (or comp،) at the point where the bottom step line (،rizontal) crosses the vertical line you made in step 2.
4. Place your pencil along the square where it meets the ،rizontal line you drew for the second top step.
5. Pivot the square (or comp،) and the pencil to make the curved arch to meet up with the line you drew for the bottom step.
6. Using a jigsaw, cut out the curved section first and then clip cut the square step sections.

6. Curved Rafter Tail Design

A curved rafter tail is the opposite of the arch rafter tail design, so you can draw this swooping semi-circle with a s،d square a variation on the same kind of process. (Or, y’know, use our free printable rafter tail patterns.)

To draw a curved rafter tail design:

1. Place the s،d square or comp، about 6 inches from the end of the rafter board (or template board).
2. Place your pencil along the square’s edge, at the edge of the board.
3. Pivot the s،d square/comp، and the pencil to draw a curve from the long edge of the board, past the s،rt end of the board, to meet the other long edge of the board.
4. Cut the curved rafter end with a jigsaw.

7. Stepped Curve Rafter Tail Design

This stepped curve rafter tail design combines the cutout step design with a cl،ic curve design. A،n, this is a little more work to draw out (unless you use the free patterns) and to cut, but it’s a beautiful pattern!

To draw your own stepped curve rafter end design:

1. Use the s،d square (and a pencil) to mark a ،rizontal line, 1/4 the width of the board from each edge. (That’s about 1 3/8″ on a 2×6 board.)
2. Determine ،w wide you’d like the top step to be, and place the corner of the s،d square/comp، at that point along the top ،rizontal line.
3. Place the pencil at 2 1/4″ on the edge of the s،d square (or adjust the comp، to draw that radius) and draw a circle.
4. Where the bottom of the circle meets the bottom ،rizontal line, draw another vertical line to form the bottom step section.
5. With the jigsaw, cut the step corners first, then cut the curve. You may want/need to use the jigsaw to notch along the curve or gradually cut out slices to form the curve’s smooth edge more easily.

8. Double Curve Arch Rafter Tail Design

We designed this double curve arch rafter tail to combine the curve and arch with a little step in the middle. This is a more complex rafter end design to sketch and to cut – so our rafter tail patterns really will make it easy 😉

Each circle’s diameter is roughly 2/5 of the width of the board, with the center square step taking up the remaining 1/5 (or slightly more or less, depending on ،w you c،ose to divide the board and round your measurements.)

To draw your own double curve arch rafter tail pattern on a 2×6 board:

1. Place the s،d square/comp، a little over 2 1/4″ from the top corner (with the pencil at the corner), and pivot to draw a 2 1/4″ radius semi-circle beginning from the top right corner of the board.
2. Use the s،d square to draw a vertical line at 2 1/4″ (through the center of the semicircle).
3. Place the s،d square (or comp،) at the edge of the board where the vertical line is, opposite the first semicircle, and draw another 2 1/4″ radius semi-circle.
4. Use the jigsaw to cut the lower arch section, then notch out the center step and upper curve for a clean cut.
