Start with the part most pages like this leave out. Ledgebay does not make a large-print or low-vision kit. Our numbers are small, and the most common criticism in our own customer reviews is that they are hard to read. Twelve reviewers have said some version of it, and more than one mentions reaching for a magnifying glass.
So this is not a page recommending a kit designed for low vision, because we do not sell one and we are not going to pretend otherwise. It is a page about what genuinely makes a numbered canvas workable when your sight is limited, based on what our own customers have told us and on what the format can and cannot do.
The single biggest lever is canvas size

The same design printed larger has larger regions and larger numbers. Going from the 12x16 to the 16x20 gives you roughly two-thirds more canvas area, and every printed shape and digit comes out around a quarter to a third bigger. That is a bigger improvement than any tool you can buy, and it costs very little.
If sight is the deciding factor, buy the largest version of whatever design you choose, every time. Do not buy the small one because the design is prettier at that size in the photograph.
Judge the design by how big its shapes are
Difficulty in a numbered kit has almost nothing to do with the subject and everything to do with how finely the artwork is divided. You can assess this yourself from the design image before you buy, and it takes about ten seconds: look at the picture and ask how much of the canvas is covered by its three or four largest shapes.
A design where sky, water and sand take up most of the surface is workable. Be Still is a beach at sunset with one chair, a broad sky and an open stretch of surf, and most of the canvas is made of large, calm areas. House Near the Lake is a night scene with a wide sheet of reflecting water. Both give you long stretches of painting where you do not have to squint at anything.
The designs to avoid are the crowded ones, however lovely they look. Orchard Puzzle has a dozen songbirds packed onto blossoming branches, each bird made of many small color patches. Bamboo Tiger is fur and grass blades, which means hundreds of narrow slivers. Neither is a good choice if reading the numbers is already work.
Light matters more than magnification
Most people reach for a magnifier first. Light usually helps more, and it helps immediately.
Put a lamp directly over the canvas rather than behind your shoulder, so it is not your own head casting the shadow. A daylight-temperature bulb is worth the small extra cost, because it renders the paint colors closer to true, and matching a pot of paint to a number is half the task. If a region is genuinely unreadable, tilting the canvas so the light rakes across the surface will often make the printed line show up as a shallow ridge you can see even when you cannot read the digit.
Magnification that leaves both hands free
A handheld magnifier means one hand is occupied and the brush hand is unsupported, which is the wrong trade. A magnifier on a stand or a clamp arm, ideally one with a light in the ring, lets you keep the brush in one hand and steady it with the other. Clip-on spectacle magnifiers work well for the same reason.
The reference print is the accessibility feature
Every kit includes an 11x17 reference print of the finished painting. It is there so you can see what a region is supposed to become before you paint it, and it is the most useful thing in the box for anyone working at the limit of their sight.
Two things make it better. First, photograph it with a phone or tablet and zoom in. On a screen you can magnify a corner of the print far past what any lens will do, and you can hold it at whatever distance suits you. Second, photograph the canvas itself the same way. If you cannot read a number on the canvas, take a close photo of that patch and zoom in on it. That single habit solves most unreadable regions, and it costs nothing.
Work in a way that does not depend on reading every number
Pick one color and fill every region carrying that number across the whole canvas before you move on. It sounds slower and it is faster, because you are only reading the canvas to confirm a number you already expect, rather than identifying one from scratch each time. Mark each number off on the reference print as you finish it, so losing your place costs seconds rather than a session.
Two more habits worth having. Rest a sheet of plain white paper under your painting hand, so the hand does not disappear against a dark region. And work in short sittings. Eye strain builds quietly, and a numbered canvas will still be there tomorrow.
What we will not claim
Some pages promise that a single coat of paint covers the printed numbers completely. That is not reliably true, and it is least true of exactly the colors you are most likely to be laying down over a dark printed digit. Whites, creams and pale yellows generally need a second thin coat. Expect that, let the first coat dry properly, and it stops being a problem.
We also will not tell you that a numbered canvas suits every degree of sight loss. It does not. It is a printed grid of small shapes with small digits, and there is a point past which no lamp or lens makes that workable. If you are buying this as a gift and you are not sure, the honest move is to ask first.
The largest canvas we make
If size is the thing that decides it, Custom Paint by Numbers goes up to 18x24, which is larger than any stock design, and you choose the photograph it is built from. A simple, high-contrast image with a large subject and few fussy details converts into fewer and bigger regions than a busy one. A single face, a house, a dog against a plain background: all of these produce a far more workable canvas than a crowded landscape.
If you want to see how the designs look finished, the customer gallery is full of photographs sent in by people who painted them, at a size you can zoom into. And if this is a first kit, the beginner's guide covers how to set up before you start.
