The phrase measure twice, cut once isn’t just about craftsmanship — it’s a quiet warning against assumptions. A second look can prevent damage that a first glance never saw coming.
In disability spaces, this wisdom becomes more than metaphor. Whenever a button sits just out of reach, a form is poorly designed, or an interface doesn’t fit the user’s needs, it reveals a system that builds before it listens. When things go wrong, the consequences don’t fall on the designer—they fall on the person who was excluded from the process. The impact of a misstep often doesn’t fall where the error occurred, but instead affects the person who was left out of the planning.
A Small Moment at the Checkout
The store was busy when a woman named Dana approached the checkout. She steadied herself with one hand on her walker while using the other to sort her groceries. One by one, she placed her items on the conveyor—bananas, rice, a frozen pizza, a can of beans, and a bottle of aspirin—the bare necessities. Everything was fine until it came time to pay.
The card reader was angled up and affixed to the top of a tall counter. It swiveled, but only slightly, and not nearly enough. Dana reached, stretched, adjusted her grip, and tried to tap. The device blinked, reset, and blinked again.
The clerk leaned forward to help. “Oh, yeah, it’s kind of weird. You just have to hold it at the right angle.”
Dana smiled politely and tried again, twisting awkwardly. Eventually, the tap registered. With the receipt in hand, she turned slowly, her back stiff from the effort. No one had meant to create friction. Still, the friction remained: subtle, repetitive, and quietly exhausting. It was not a barrier exactly, just a quiet, daily inefficiency that had become routine.
When Design Doesn’t Fit Everyone
Everyday design choices reflect values—not always consciously, not always unkindly, but clearly. Devices are built with assumed reach. Doorways are constructed with assumed stride. Websites are designed with assumed speed.
In each case, the design works—until it doesn’t. When it fails, it is the person left bending, stretching, or backtracking to make it work, because the original plan never included them.
The phrase measure twice, cut once suggests there’s a chance to get it right before any harm is done. For many people living with disability, the adjustment often comes after the cut, after the design is finalized and the impact is already felt.
Beyond the Checklist
Accessibility is often treated as an add-on, folded into a checklist or addressed after feedback. That approach assumes the original design was neutral. It rarely is.
Measuring twice means taking a moment to pause before building, not waiting until concerns arise. It means designing with the diversity of people’s needs and abilities in mind from the start. It also means recognizing that meeting codes and compliance doesn’t always guarantee something will work well in practice.
The aim isn’t to get everything perfect. It is to take care where it’s possible, and to avoid creating difficulty that thoughtful design could have removed.
Ordinary Places, Unseen Obstacles
They are easy to overlook—small details, brief interactions, and tasks most people complete without a second thought. Yet for others, these moments are points of friction, shaped by choices they had no say in.
- A pharmacy with only one accessible aisle, partially blocked by a seasonal display
- A touchscreen parking meter that doesn’t respond well to prosthetics
- A school sign-in system that assumes parents speak, hear, type, and see in specific ways
- An online form that times out before screen readers can finish navigating it
None of these are unusual. Each one is the result of designing too fast, measuring too narrowly, or never checking the angle of someone else’s view.
It’s the Design That Matters
Variation is the rule, not the exception. When design overlooks difference, the friction that follows is often seen as an individual hurdle, something to be met with a little more strength, patience, or grace.
What is really needed is something simpler: a second measurement. Because listening, testing, and slowing down aren’t delays—they’re how design begins to include everyone. They are investments in making things work well for anyone who comes through the door.
A Simple Pause, A Different Outcome
The first cut always carries risk. Taking time to measure again, to consider the many ways people move, think, and navigate, is more than careful planning. It is essential.
Dana didn’t file a complaint or request any changes. She adjusted, as she always did, and moved on. Yet the moment stayed with her. The checkout could have been easier to use with just a bit more attention—a simple pause, a second look, a single extra measurement would have made the difference.
Every builder, designer, and planner—everyone who shapes the spaces we move through each day—holds a quiet power: the power to choose. That power begins with a moment of care, with a pause before the cut and a second glance at the plan. Inclusion takes root in small, deliberate choices. It comes from the decision to design something that works not just for most, but for all.
