Mark the path for a box to come out, and confirm you have room to assemble and anchor the exact unit as directed. ## Measure the site at floor, shelf and top height Choose the exact position and draw the nearest obstructions. Measure between walls, cabinets or door frames at floor level, midway up and near the proposed top. Check both the front and back of the space. Walls can be out of square and a narrower point near the floor can prevent the frame from going in. Record the smallest useful reading rather than averaging the figures. Note where skirting, pipes, sockets and radiator controls project. Measure the skirting height and how far it comes out from the wall. Compare that with the back, feet and any cross-brace shown in the assembly drawings. Some frames clear the skirting and others stand forward. Use the actual planned position for your installed depth and confirm how the fixing works with any gap behind the unit. Check the floor as well. A thick mat or change in floor level can leave a foot unsupported. Look for a flat, suitable position and use a level if the floor looks uneven. Use any levelling feet only as the instructions allow. Leave fixed fittings, ventilation and controls accessible. ## Mark the space you need in front Tape the proposed footprint onto the floor, including any stand-off from the wall. Place a representative loaded box or a safe empty template in front and rehearse the withdrawal. Allow room for your hands at the sides, the distance the box must move to clear the shelf and any lift over a lip. If there is a door nearby, open it in its normal position and check the route again.

The box and your feet both need somewhere to go. **Illustrative installed footprint.** A 26 cm-deep unit sits 2 cm forward of the wall. Its front is 28 cm from the wall before any box or handle. If the opposite obstruction sits 110 cm from the wall, 82 cm remains before you withdraw a box. Test that working area with the door, box and your normal stance. For a regularly used box, check where you can set it down once it is out. A deeper unit may fit an alcove but need too much room in front of it. Compare [shallow shelving](https://spacemadeuseful.co.uk/best-shallow-freestanding-shelving/) where the wall depth is tight. The [shelf bay measuring guide](https://spacemadeuseful.co.uk/measure-shelves-for-storage-boxes/) covers the support surface and usable gap above the box. ## Check how the unit gets into place Read the assembly sequence before buying. Find out if the frame is assembled flat, in sections or upright. Measure a separate work area for the parts, tools and people required by the instructions. A unit can fit the final ceiling height but need more room during assembly or while it is raised into position. Check overhead fittings and leave room to handle the longest piece. Where the instructions call for raising an assembled unit from the floor, sketch the side profile and mark the far corner as it turns. For example, a rigid rectangle 180 cm high and 40 cm deep can sweep about 184.4 cm high when rotated about its bottom corner. That estimate excludes projecting feet, hands and uneven flooring. Check the actual lifting method and allow working room above it, including the space needed to install the wall restraint. Measure the delivery route for the packaging and the longest part. If you need to build away from the alcove, check the route for moving the frame into place. Keep the assembly and moving sequence within the maker's instructions. If you cannot carry out the recommended steps in the available room, use a suitable assembly service or choose a different unit. ## Plan the fixing and the loaded layout Check the exact restraint, fitting locations and wall requirements. Leave room to reach the specified fixing point and use hardware suitable for the wall material. If you cannot identify the wall or confirm a safe fixing, get help from a competent installer. Where a wall fixing is required, resolve the mounting position before loading the shelves. Sketch the first shelf layout using the outside size and weight of each filled box. Give heavier boxes a suitable low position and the most-used groups an easy grip. Compare with the documented shelf and unit limits and follow the stated loading pattern. Mark the usable width between uprights and measure the gap to the underside of the shelf above. Once the unit is assembled and secured as directed, check a representative box before filling the rest. The [box shelving guide](https://spacemadeuseful.co.uk/best-shelving-for-storage-boxes/) compares shelf surfaces and spacing options. For a sloping space, use the [under-stair shelving plan](https://spacemadeuseful.co.uk/plan-shelving-under-stairs/) to measure both front and rear profiles. Read the [shelving load-rating guide](https://spacemadeuseful.co.uk/read-shelving-load-ratings/) before assigning dense boxes to a level. ## Questions before you choose ### Do I measure from the wall or skirting? Measure both. The skirting can hold the frame forward, while the wall determines the position of a fixing. Check the assembly drawing to see where the frame sits. ### Does freestanding shelving need a wall fixing? Follow the exact assembly and securing instructions. Many floor-standing units require a wall restraint or fixing. ### How much space should I leave to pull boxes out? Check the full loaded box, its handle, the lift over a shelf lip and where you can stand. Use a full-size mock-up if the space is close. ### Can I assemble a tall unit in an alcove? Check whether the instructions call for assembly upright or on the floor. Include access to the fasteners, room for handling the panels and any space needed to raise the unit. ### Is the outside depth the usable shelf depth? Use the supported shelf surface and its clear width between posts, lips and braces. Outside measurements describe the frame. ### What if the floor slopes? Check the model instructions for suitable flooring and any levelling system. If it cannot sit level and secure as directed, change the position or choose a suitable unit. ## How we put this guide together The plan and figures are illustrative. We reviewed manufacturer assembly and anchoring guidance to separate installed footprint, assembly room and the space required to withdraw a box.
