A shed ramp can make it easier to move a mower, bicycle, or garden cart across a raised doorway. But a useful ramp needs more than a board resting against the threshold.
Its slope must suit the equipment. Its width must accommodate the wheels and handling space. Its supports and connections must carry the intended loads without shifting.
Plan the ramp alongside the entrance whenever possible. A shed that sits higher than expected can require more approach space than you originally allowed.
This guide focuses on equipment access. A ramp intended for wheelchair or other accessible use needs a separate design addressing the applicable accessibility requirements.

Planning a shed with wheeled access? Explore My Shed Plans. Check the floor height and doorway arrangement before deciding what ramp the building will need.
Start With What Will Use the Ramp
A wheelbarrow, push mower, riding mower, and bicycle have different dimensions and handling requirements.
List the equipment you intend to move and check its instructions for ramp use.
Record:
- Operating or transport weight.
- Width across the wheels.
- Overall equipment width.
- Wheelbase, where relevant.
- Ground clearance.
- Permitted operating or loading conditions.
- Any attachments that affect clearance.
Do not assume a ramp suitable for a light garden cart will also carry a riding mower.
For powered equipment, follow the manufacturer’s instructions about how it may be moved on a ramp. A general slope rating for operating on grass does not automatically establish safe ramp use.
Measure the Entrance Before Choosing a Ramp
Take measurements from the completed or accurately specified entrance.
| Measurement | Why it matters |
|---|---|
| Rise | Establishes the vertical difference the ramp must overcome |
| Available horizontal run | Determines how much approach space is available |
| Clear door opening | Limits the usable equipment width |
| Threshold profile | Affects the transition into the shed |
| Door swing | Determines whether the ramp obstructs operation |
| Ground level across the approach | Reveals uneven support conditions |
| Turning space | Determines whether equipment can line up with the ramp |
If the foundation is still being planned, coordinate the finished floor height before construction.
Our guides to shed doors and shed foundation options cover those related decisions.
Understand Rise, Run, and Ramp Length
These measurements are different:
- Rise: The vertical height difference.
- Run: The horizontal distance covered.
- Ramp length: The distance along the sloping surface.
Slope can be expressed as rise divided by run.
A Simple Geometry Example
Suppose an entrance is 6 inches above the ramp’s lower support and the available horizontal run is 72 inches.
The slope ratio is:
6:72 = 1:12
The sloping length is approximately 72.25 inches, before allowing for any connection or transition detail.
This example explains the measurements. It does not establish that the slope, length, or structural arrangement is suitable for your equipment.
Use the relevant equipment and ramp requirements to decide what is acceptable.
Check Ground Clearance as Well as Slope
A mower can fit within the ramp’s weight rating and still scrape at the top.
The point where the sloping ramp meets the shed floor creates a change in angle. Equipment with a long wheelbase or low deck may have difficulty crossing that transition.
Ramp suppliers use loading height, wheelbase, and ground clearance when assessing suitability.
Do not choose by ramp length alone.
Review Both Ends
Check the transition:
- From the ground onto the ramp.
- From the ramp across the threshold.
- From the threshold onto the shed floor.
An abrupt lower lip can catch small wheels. A raised threshold can create a second obstacle even after the equipment reaches the top.
Ask the ramp supplier or designer to confirm compatibility with the measured entrance and equipment.
Choose the Width Around Actual Use
The ramp should suit the doorway and the equipment’s movement.
For a full-width ramp, consider wheel positions, steering tolerance, and any space needed by someone walking beside the equipment.
For separate wheel tracks, check every wheel’s path. Front and rear wheel spacing may differ, and a narrow-wheel cart may not suit the same arrangement.
Do not assume two narrow ramps provide a suitable walking surface.
Keep the Doorway Usable
Check whether the ramp interferes with outward-opening doors, latches, or the threshold.
A ramp that prevents the doors from closing properly has not been coordinated with the entrance.
If the door arrangement is still undecided, review our shed doors guide.
Permanent vs. Removable Ramps
| Arrangement | Potential advantage | What to check |
|---|---|---|
| Permanent ramp | Ready whenever equipment is moved | Support, attachment, drainage, and door clearance |
| Removable ramp | Can free the entrance when not in use | Secure positioning, storage, and handling weight |
| Full-width surface | Can suit varied wheel paths | Complete structural capacity and usable width |
| Separate wheel tracks | May suit particular equipment | Wheel alignment, individual track capacity, and compatibility |
Choose according to how frequently the ramp will be used and who will position it.
A removable ramp should not depend on friction alone unless that is explicitly part of an approved system.
Understand the Load Rating
For a purchased ramp, read the capacity information carefully.
Confirm whether the rating applies to:
- One ramp or a pair.
- A particular wheelbase.
- A specified loading height.
- A defined load distribution.
- Equipment alone or the complete permitted load.
Account for attachments, carried contents, and an operator if the permitted use includes one.
For a site-built ramp, obtain a suitable design for the intended loading. Board thickness alone does not establish the capacity of the supports, decking, and connections.
The shed entrance and floor must also carry the equipment. Our shed floor framing guide explains why the complete support system matters.
Want to coordinate the entrance before building? Take a look at My Shed Plans. Review the floor and doorway details, and clarify how a suitable ramp can connect to the chosen design.
Compare Timber and Manufactured Ramps
Site-Built Timber Ramp
A timber ramp needs drawings or specifications covering:
- Supporting members.
- Decking.
- Bearing locations.
- Connections.
- Suitable materials for the exposure.
- Fasteners.
- Surface treatment or traction details.
- Any required edge protection.
Do not attach a ramp to siding or decorative trim and assume the connection is structural.
Manufactured Ramp
A manufactured product may provide defined installation conditions and a published capacity.
Check whether it is intended for permanent outdoor use, temporary equipment loading, or another application. Not every loading ramp is designed to remain at a shed entrance.
Confirm how it is secured, supported, inspected, and stored.
Manufacturer-Specific Shed Accessories
Some shed suppliers offer ramp systems that connect to particular sill arrangements.
That can simplify compatibility, but only for the intended building. Do not copy a proprietary attachment onto an unrelated shed without review.
Prepare Stable Supports
The lower end of the ramp needs a suitable bearing arrangement. Its upper end needs the specified support and restraint.
Inspect the approach for soft ground, erosion, and water collection.
Do not level a ramp using loose scraps that can move during use. If the entrance or ground level changes, reassess the arrangement.
Our ground preparation guide explains the preliminary site checks.
For permanent work, coordinate the ramp with the building’s drainage and required siding clearances.
Plan Traction and Water Management
The ramp surface must suit the intended use and exposure.
Check the manufacturer’s guidance or the design’s surface specification. Wet leaves, mud, algae, frost, or worn surfaces can affect grip.
Do not assume that an aggressive surface treatment solves an unsuitable slope or unstable support.
Also avoid creating a detail that holds water against the shed entrance. Preserve the door and wall system’s intended drainage paths.
Any added strips, coatings, or coverings should be compatible with the ramp and should not create an obstruction for small wheels.
A Practical Planning Sequence
1. Identify the Equipment
Gather dimensions, weight, clearance, and manufacturer instructions.
2. Measure the Entrance
Record rise, available run, doorway width, threshold shape, and ground conditions.
3. Select a Suitable System
Choose an appropriately rated product or obtain a design matched to the project.
4. Confirm the Connections
Check the upper attachment and lower support before buying materials.
5. Resolve Door and Drainage Conflicts
Make sure the ramp works with the entrance and surrounding ground.
6. Install and Inspect
Follow the complete instructions and inspect the finished arrangement before use.
Do not use heavy equipment as an improvised proof test for an uncertain ramp.
Budget for the Complete Ramp
Include more than the surface material.
Possible expenses include:
- Framing and decking or the manufactured ramp.
- Connection hardware.
- Ground preparation.
- Required supports.
- Compatible finishes.
- Tools.
- Delivery.
- Installation help.
Record the components in your shed materials list and add the total to your shed-building budget.
If the shed is not yet built, planning the entrance height early may help avoid an unnecessarily complicated approach.
Common Shed Ramp Mistakes
Choosing Length Without Checking Rise
The same ramp produces different slopes at different entrance heights.
Ignoring the Mower Deck
Check ground clearance and the transition at the top.
Reading a Pair Rating as an Individual Rating
Confirm exactly how capacity is stated.
Attaching to Nonstructural Trim
Use the specified structural connection.
Forgetting the Door Swing
Check the full operating path before installation.
Letting the Lower Support Deteriorate
Inspect for movement, erosion, and soft ground.
Frequently Asked Questions
How long should a shed ramp be?
It depends on the rise, equipment requirements, ground clearance, and selected ramp system. Measure the entrance before choosing a length.
What slope should a mower ramp have?
Follow the mower and ramp manufacturers’ applicable instructions. Do not use a universal slope rule for every machine.
Can I use two boards as a shed ramp?
Do not assume loose boards provide sufficient strength, restraint, width, or traction. Use a suitable designed or rated arrangement.
Should a ramp be as wide as the door?
It must suit the intended equipment and entrance. Full doorway width may be practical, but the complete layout determines the requirement.
Can I attach a ramp to a resin shed?
Only using a method the shed manufacturer permits. The wall or threshold may not be designed to accept an improvised connection.
Can one ramp serve both equipment and wheelchair access?
Do not assume so. Accessible use introduces separate requirements for slope, width, landings, surface, edge protection, and other details.
Why does my mower scrape at the top?
The wheelbase, deck clearance, ramp angle, and threshold transition may be incompatible. Have the arrangement assessed rather than modifying the mower or forcing it across.
Design the Ramp Around the Entrance
A practical shed ramp matches the equipment, doorway, supports, and available approach space.
Measure first, confirm capacity and clearance, and use a suitable connection system. Keep the surface and supports in good condition so the ramp remains useful after installation.
