24" to 72"
Standard planning sizes cover sheds, garages, homes, barns, horse barns, large barns, and arenas.
1/12 to 10/12
Common roof pitches are planned as standard fit ranges. Steeper roofs can be reviewed before quote.
Confirm before cutting
Roof openings should stay smaller than the cupola base and must be confirmed for your roof type.
Send photos
A straight-on photo, building width, roof pitch if known, and ZIP code are enough to start.
Not sure about size, pitch, or opening details?
Send what you know. We can help confirm the information needed for a project-specific quote before anything is built or cut.

Cupola dimensions by nominal size.
Use this table to estimate scale before requesting exact build specs. Final dimensions and weights vary by tier, roof style, options, and project details.
| Size | Approx. Height | Base Footprint | Approx. Weight | Common Use |
|---|---|---|---|---|
| 24" | ~32" | 24" x 24" | 25-35 lbs | Garden sheds and small outbuildings |
| 30" | ~38" | 30" x 30" | 35-50 lbs | Storage sheds and single-car garages |
| 36" | ~44" | 36" x 36" | 50-70 lbs | Two-car garages and small barns |
| 42" | ~50" | 42" x 42" | 70-90 lbs | Medium barns and workshops |
| 48" | ~56" | 48" x 48" | 90-120 lbs | Large barns and equestrian facilities |
| 60" | ~68" | 60" x 60" | 120-160 lbs | Agricultural barns and event venues |
| 72" | ~80" | 72" x 72" | 160-220 lbs | Grand structures and riding arenas |
Dimensions and weights are planning references. Confirm project-specific measurements before cutting, framing, ordering flashing, or scheduling installation.
Roof pitch is planned before production.
Roof pitch is shown as rise over 12 inches of horizontal run. Example: a 6/12 roof rises 6 inches for every 12 inches of run.
Standard planning range
Typical fit range reviewed during quote.
Standard planning range
Steeper common roofs can usually be planned before production.
Extension review
May require additional pitch extension details and quote confirmation.
Custom review
Send photos, roof pitch, and measurements before quoting or installation.
Do not know your roof pitch? Send a clear photo from about 50 feet back and any measurements you have.
Confirm the opening before cutting the roof.
The roof opening should be smaller than the cupola base so the base covers the cutout and supports the flashing plan.
Opening is typically 4-8" smaller than the base overall
That usually leaves about 2-4 inches of base coverage on each side. Final opening depends on cupola size, roof type, pitch, framing, and installation plan.
| Cupola Size | Base Dimensions | Planning Opening Range |
|---|---|---|
| 24" | 24" x 24" | 16" x 16" to 20" x 20" |
| 30" | 30" x 30" | 22" x 22" to 26" x 26" |
| 36" | 36" x 36" | 28" x 28" to 32" x 32" |
| 42" | 42" x 42" | 34" x 34" to 38" x 38" |
| 48" | 48" x 48" | 40" x 40" to 44" x 44" |
| 60" | 60" x 60" | 52" x 52" to 56" x 56" |
| 72" | 72" x 72" | 64" x 64" to 68" x 68" |
Do not cut the roof opening until final cupola size, base, roof pitch, and installation plan are confirmed. For 48" and larger cupolas, have a qualified installer review framing and support before installation.
Built for exterior roofline use.
Tanasi cupolas are built for long-term exterior service, practical installation, and a finished roofline. Final materials and finish details are confirmed by tier and project options.
Pine framing
Pine framing is selected for dependable exterior use, fastener hold, and a practical balance of strength and weight.
Steel roofing
Steel roof panels provide durable exterior performance and coordinate with common barn, garage, and home roof finishes.
Prepared before shipment
Cupolas ship caulked and prepared for installation. The installer still confirms flashing and final roof sealing on site.
Pre-painted options
Factory-applied color directions can match your roofline, complement trim, or create a statement. Custom colors can be reviewed during quote.
Spec sheets, installation planning, and CAD support.
Share these resources with your builder, contractor, dealer, or architect before framing, roof opening, or installation planning.

Common planning questions.
Are these dimensions and weights exact?
No. They are planning ranges. Final height, weight, and fit can vary by cupola size, tier, roof style, options, accessories, and project details. Your quote or spec sheet confirms the project-specific details.
What if I do not know my roof pitch?
You can still request a fit check. Send clear photos of the building from about 50 feet back plus any measurements you know, and Tanasi Designs can help identify what is needed before production.
Should I cut the roof opening before my cupola arrives?
No. Do not cut your roof until your installer has confirmed the final opening size, cupola base, roof pitch, placement, flashing plan, and structural support.
Who should install the cupola?
Most customers work with a builder, roofer, contractor, or experienced project crew. Installation depends on roof type, pitch, cupola size, weight, site access, and lifting plan.
Are CAD files available?
Yes. 2D DWG files are available by request for architects, specifiers, builders, and project teams. Include cupola size, roof pitch, building type, project stage, and preferred file format.
Send the roofline. We will help confirm the fit.
If you are debating size, pitch fit, opening requirements, or CAD support, send your building details and photos. No order is placed from the fit check.
