Decision Lantern

Home and office calculator

Bed-frame size selector

Reviewed Skip to the planner

People matching a frame to a mattress size. The decision this page isolates is narrow on purpose: translate mattress size into a frame class. Fit and capacity are the expensive mistakes. Settle those before you commit to a finish or a brand.

This page produces an explainable category or size so options can be compared without a product ranking. The calculator does not rank Thuma and IKEA. It produces an explainable class so Thuma Queen, Thuma King, and IKEA MALM Queen can be compared as examples of that class.

The working method is: Convert the inputs into a published planning class using the method on this page, then compare official product pages that match that class. Planning notes are grounded in CTA. This page does not quote a price or rank a brand.

How to use this calculator

People matching a frame to a mattress size. Translate mattress size into a frame class. If you can answer mattress width, this page can produce a class you can shop against.

What this page will not do

  1. Enter the planning inputs

    Match bed-frame size by recording mattress width. Use real measurements or counts, not a rounded marketing number.

  2. Keep optional extras off until they are real

    This tool has no optional add-ons. If a number is uncertain, calculate a range and keep the more conservative class.

  3. Read the planning class

    Calculate class and treat the headline as a class, not a product name. Matching examples below follow Queen, King, and Full.

  4. Compare official pages, then verify

    Open the official page for each example in that class. Confirm current specifications, dimensions, and terms. Decision Lantern does not quote a live price or complete an install review.

Frequently asked questions

How does the bed-frame size selector work?

It converts mattress width into a planning class using a published rule. Convert the inputs into a published planning class using the method on this page, then compare official product pages that match that class. The headline is a class such as Queen, King, and Full, not a vendor ranking.

Is Thuma Queen better than Thuma King?

This page does not rank Thuma Queen, Thuma King, and IKEA MALM Queen. Thuma Queen and Thuma King are listed because they are real products with official pages that map to different or overlapping classes. The useful question is which class matches your inputs.

Can I treat the result as a buying recommendation?

This page does not quote a price or rank a brand. Use the class to decide what to read next, then verify fit, terms, and installation requirements on the official page and with a qualified installer when the product needs one.

Do the product links earn Decision Lantern a commission?

Not on the current preview. Links go to official manufacturer or service pages. If compensated links are added later, the disclosure on this page will say so in plain language.

What should I verify after I get a class?

Confirm the current specification, dimensions or plan limits, and any program terms on the official page. Manufacturer specifications and program terms can change and must be verified on official pages. The next editorial review for this page is due 2026-11-14.

Why these 3 examples?
