Masonry calculators and cutting templates

Choose your workshop: arches, circular windows, jack arches and gable weaving. With brick layouts, setting-out sizes and PDF cutting templates.

Tudor arch calculator

A Tudor arch has four circular arcs: two small shoulders and two larger arcs meeting at a pointed crown. BrickCore uses a fixed construction with shoulder radius equal to half the rise, calculating all four centres, bricks, joints and cutting dimensions.

Enter, check and download

Enter span, rise, brick size and joint. Use the shared 2D and 3D workspace. The PDF includes the calculated layout and scaled cutting templates. The free Dutch guide explains manual setting out in 20 steps using your dimensions.

Segmental arch calculator

A segmental arch follows part of a circle above an opening. The span and rise determine its curvature. BrickCore draws the arch, distributes the bricks and shows how the joints meet.

Enter, check and download

Enter the clear span, rise, brick dimensions and joint width. Check the radius, springing points and brick layout. Download the setting-out drawing and full-size cutting profiles for A4 or A3.

Semicircular arch calculator

A semicircular arch has the shape of half a circle. Its intrados radius is half the opening width. The brick division and joints determine how the masonry closes at the crown.

Enter, check and download

Enter the opening, brick size, arch thickness and target joints. Inspect the calculated bricks and connections. The PDF includes the setting-out shape, brick profiles and a 10 cm scale check.

Pointed arch calculator

A pointed arch joins two curved sides at a pointed crown. Its width and height determine the shape. BrickCore calculates both sides together so you can inspect the brick division at the apex.

Enter, check and download

Enter span, height, brick dimensions and joints. Check the springing points, radii and crown connection. Use the 2D drawing, 3D inspection and full-size PDF profiles for setting out.

Rampant arch calculator

A rampant arch connects springing points at different heights. BrickCore lets you choose the higher side and set the side angles. The drawing shows how bricks span the unequal springing levels.

Enter, check and download

Set the opening and level difference first, then the brick size and joints. Inspect both side connections and the depth in 3D before downloading the PDF workshop sheets.

Basket-handle arch calculator

A basket-handle arch combines circular arcs into a low, broad profile. The selected shape determines the transition from the sides to the centre. BrickCore uses this geometry to divide the bricks and joints.

Enter, check and download

Choose the basket-arch shape and enter opening, rise and brick dimensions. Inspect the joins between the arcs. The calculation provides setting-out dimensions and individual profiles for the chosen brick layout.

Elliptical arch calculator

An elliptical arch follows an ellipse. Its curvature changes along the arch, so the brick layout needs its own calculation. BrickCore computes the curve and the corresponding brick and joint geometry.

Enter, check and download

Enter width, rise, brick dimensions and joints. Check the layout from springing to crown. Download the elliptical outline and individual cutting profiles as full-size A4 or A3 PDF sheets.

Circular window and oculus calculator

A circular window has a complete masonry ring around the opening. Its brick division must close through 360 degrees. BrickCore calculates the bricks and joints around the ring and the individual cutting profiles.

Enter, check and download

Enter diameter, ring thickness, brick dimensions and joint width. Check the closure and quantities. Download the circular setting-out template and full-size cutting pieces on numbered sheets.

Jack arch and flat arch calculator

A jack arch divides tapered bricks above an opening. BrickCore calculates each brick and joint for a flat or cambered profile. The workshop starts with a depth of 10 cm.

Enter, check and download

Enter span, height, brick dimensions and joint width. Check the brick plan and connections. The PDF includes a complete overview, brick numbers and individual full-size cutting profiles with setting-out dimensions.

Dutch gable weaving calculator

Dutch gable weaving connects inclined masonry along the roof line to horizontal wall courses. Choose the number of courses per tooth. The top two sections on each side have their own shortened pieces.

Enter, check and download

Enter gable width, rise or roof pitch, brick size and course gauge. The PDF includes the reusable mould, stop lines for the upper two sections and all cut pieces, with numbers and separate profiles for the closing pieces.

Frequently asked questions

Which masonry arches can BrickCore calculate?

BrickCore calculates segmental, semicircular, pointed, rampant, basket-handle and elliptical arches. It also divides complete circular windows or oculi. Each shape has its own calculator with brick layout and workshop sheets.

Does BrickCore calculate jack arches and gable weaving?

Yes. Separate workshops cover flat and cambered jack arches and Dutch gable weaving. Gable weaving includes the reusable mould, stop lines and cutting profiles for the shorter upper sections.

Can I print the template at true size on A4 or A3?

Yes. Download the PDF and print at Actual size or 100%. Align the numbered sheet edges and check the scale with the 10 cm line. Choose A4 or A3, portrait or landscape. One complete PDF costs 1 credit, regardless of page count.
