How to Calculate TV Price Per Inch (With Real 2026 Data)

The Formula: TV Price Per Inch in One Step

Price per inch = total price ÷ diagonal screen size. Nothing else goes in the denominator — not the stand height, not the shipping weight, just the diagonal inches printed in the listing title.

Here is the formula applied to two 65-inch OLED listings from our live tracker. The Samsung 65-inch S84F sits at $950, so $950 ÷ 65 = $14.62/inch. The LG OLED65C5P, also 65 inches, sits at $1,164 ÷ 65 = $17.91/inch. Identical screen size, $3.29/inch apart (17.91 − 14.62), and $214 apart in total. That gap is exactly what this metric exists to expose before you click buy.

If you have used our storage guides, you already know this math — it is the same normalization as price per GB, with inches swapped in for gigabytes. The full price-per-GB walkthrough covers the identical logic for SSDs, SD cards, and RAM.

Worked Examples from September 2026 Live Listings

We validate the formula against live in-stock listings on our tracker, current as of September 19, 2026 — not MSRPs, not historical lows, not third-party marketplace claims.

The cheapest in-stock per-inch price in the entire 4K LED category right now belongs to the Pioneer 55-inch LED 4K Xumo TV →: $190 ÷ 55 = $3.45/inch. The cheapest OLED listings — LG's 55-inch B6E and Samsung's 55-inch S84F, tied at $800 — both work out to $800 ÷ 55 = $14.55/inch. Same 55-inch diagonal on both sides of that comparison: $14.55 ÷ $3.45 ≈ 4.2× more per inch for OLED. Whether that premium is worth it is your call. The math just makes the size of it undeniable.

Same-size comparisons are where the metric earns its keep. On 50-inch listings, the Insignia F50 LED runs $180 ÷ 50 = $3.60/inch while the VIZIO VQD50M QLED → runs $194 ÷ 50 = $3.88/inch — a $0.28/inch difference (3.88 − 3.60) between two TVs of identical size. And at 55 inches, the Insignia F50 LED at $3.64/inch sits just $0.19/inch above the Pioneer's $3.45/inch LED floor.

One more distinction the raw listings make obvious: floor is not average. Across the five cheapest 4K LED listings ($3.45, $3.49, $3.49, $3.60, $3.64), the average is (3.45 + 3.49 + 3.49 + 3.60 + 3.64) ÷ 5 = $3.53/inch. The $3.45 floor is one specific TV — the Pioneer 55-inch — not what a typical listing costs.

What Your Number Means: LED vs QLED vs OLED Floors

The floor price per inch for in-stock models at time of writing is $3.45 for 4K LED, $3.88 for QLED, and $14.55 for OLED. Those are the cheapest in-stock listings on our tracker, not market averages, and how we source prices and compute rankings is documented in our methodology.

One caveat before you quote those floors at a retailer: they come from different screen sizes. The LED floor is a 55-inch Pioneer, the QLED floor is a 50-inch VIZIO VQD50M ($194 ÷ 50 = $3.88/inch), and the OLED floor is a 55-inch LG B6E. Category floors answer "what is the cheapest tracked TV in this class" — for a size-matched verdict, compare listings at your own diagonal, like the 50-inch pair above ($3.60 LED vs $3.88 QLED).

The OLED table shows a pattern worth internalizing. LG's 48-inch B6 sits at $800 ÷ 48 = $16.67/inch, while the 55-inch B6E at $800 ÷ 55 = $14.55/inch is $2.12/inch cheaper (16.67 − 14.55). Same brand, same series family, same $800 price — the smaller screen costs more per inch. And Samsung's 65-inch S84F at $14.62/inch is cheaper per inch than LG's 48-inch B6 despite being 17 diagonal inches bigger.

Three Mistakes That Make Price Per Inch Lie

Mistake 1: Treating diagonal inches as picture quantity. Screen area grows with the square of the diagonal, so a 65-inch TV at an identical $/inch to a 55-inch is not delivering the same picture-per-dollar — the larger diagonal adds more actual screen than the inch count suggests. Use price per inch to compare within a size or technology class, never as a measure of raw screen real estate.

Mistake 2: Treating the floor as the average, or comparing floors across sizes. The five cheapest LED listings average $3.53/inch against a $3.45 floor — close, but not the same number. Worse is cross-size floor abuse: saying "QLED costs more than LED" from a $3.88 floor built on a 50-inch VIZIO VQD50M versus a $3.45 floor built on a 55-inch Pioneer mixes diagonals. Also check what you are actually comparing: three of the five cheapest QLED listings — the TCL Q3K, Toshiba V45, and Hisense QD4SR at $160 ÷ 40 = $4.00/inch each — are FHD/1080p models per their own listing titles, not 4K.

Mistake 3: Assuming bigger is always cheaper per inch. It usually helps within a series — LG's B6 line drops from $16.67/inch at 48 inches to $14.55/inch at 55 inches — but it is not a law. The 65-inch LG C5 at $17.91/inch costs more per inch than the 55-inch LG B6E at $14.55/inch, and the 58-inch Hisense QD50 at $3.97/inch barely undercuts the 40-inch QLED trio at $4.00/inch. Series and panel class move the number as much as size does. If you are shopping the cheap end regardless, our budget 4K LED picks rank live listings by this exact metric.

Frequently Asked Questions

How do I calculate price per inch for a TV?

Divide the listing price by the diagonal screen size in the title. Example from our tracker: the Pioneer 55-inch LED 4K Xumo TV at $190 ÷ 55 = $3.45/inch. Two 43-inch LEDs — the Pioneer Roku model and the Insignia F50 — both list at $150 ÷ 43 = $3.49/inch, which also shows the metric's limit: when prices tie, other factors have to break it.

What is a good price per inch for a 4K TV in 2026?

Benchmark against the in-stock floors at time of writing: $3.45/inch for 4K LED (Pioneer 55-inch), $3.88/inch for QLED (VIZIO VQD50M, 50-inch), and $14.55/inch for OLED (LG B6E and Samsung S84F, both 55-inch). A listing at or near its class floor is among the cheapest we track; anything well above it needs a reason.

Is OLED worth the higher price per inch compared to LED?

Price per inch quantifies the premium; it cannot judge picture quality. The size-matched version: the 55-inch LG B6E at $14.55/inch versus the 55-inch Pioneer LED at $3.45/inch, a ratio of 14.55 ÷ 3.45 ≈ 4.2×. If that premium buys you something you will see every day, that is your call — the metric's job is to make sure you know you are paying it.

Do bigger TVs have a lower price per inch?

Often, but not reliably. LG's B6 OLED falls from $16.67/inch at 48 inches to $14.55/inch at 55 inches, and Samsung's 65-inch S84F at $14.62/inch beats LG's 48-inch B6. Yet the 65-inch LG C5 at $17.91/inch is more per inch than every 55-inch OLED on our list. Check the live tables at your target size instead of assuming a size discount.

Are TV prices going up in September 2026 because of the memory shortage?

We track listing prices, not component markets, and we will not speculate about memory costs. What we can verify as of September 19, 2026: the cheapest in-stock floors on our tracker are $3.45/inch LED, $3.88/inch QLED, and $14.55/inch OLED, and the live tables update as listings move. Watch the floor for your target size — that is the number that will tell you if prices actually shift.
