USPS Media Mail is a cost-effective shipping service offered by the United States Postal Service specifically for certain types of media and educational materials. It provides a significantly lower rate than Parcel Select Ground or Priority Mail, making it an attractive option for businesses and individuals shipping eligible items like books, sound recordings, video recordings, printed music, and film.
Eligible Items for Media Mail:
Books (containing at least 8 printed pages, no advertising)
Manuscripts
Music manuscripts
Sound recordings (e.g., CDs, DVDs)
Video recordings (e.g., Blu-rays, DVDs)
Printed sheets of music
Play manuscripts
Sheet music
Computer media (e.g., diskettes, CD-ROMs, memory cards)
Certain test materials used for standardized tests
Ineligible Items:
It's crucial to understand what is not allowed in Media Mail shipments. Sending ineligible items can lead to significant delays, fines, or the parcel being returned to the sender. Prohibited items include:
Personal correspondence
Blank recordable media
Items with advertising (except for books with limited advertising pages)
Magazines and newsletters with more than 5% advertising
Video games
Magazines or catalogs not meeting Media Mail criteria
Other merchandise or business communications
How Media Mail Pricing Works:
USPS Media Mail pricing is based primarily on the weight of the package. While USPS has dimensional weight pricing for some services, Media Mail's primary pricing component is the actual weight. However, oversized packages can incur additional fees.
The general pricing structure for Media Mail (as of recent USPS rate charts) is a base rate for the first pound, and then a lower rate for each additional pound or fraction thereof.
Important Considerations:
Weight Limit: Media Mail packages can weigh up to 70 lbs.
Size Limits: Standard size limits apply, but oversized packages (over 108 inches in combined length and girth) will incur additional postage. The calculator below primarily focuses on weight and does not incorporate complex dimensional surcharges for extremely large items, which are determined by USPS based on combined length and girth.
Inspection: USPS reserves the right to inspect the contents of Media Mail packages to ensure they comply with eligibility requirements.
Delivery Time: Media Mail is the slowest USPS service, often taking 2-8 business days for delivery, sometimes longer depending on distance.
Using the Calculator:
This calculator provides an estimated cost for sending a package via USPS Media Mail. You need to input the package's weight in pounds and its dimensions in inches. The calculator uses a simplified pricing model based on current USPS rates for Media Mail. Please note that the USPS rates are subject to change. For the most accurate and up-to-date pricing, always refer to the official USPS website or visit a USPS Post Office. This tool is intended for quick estimates and planning.
Disclaimer: This calculator is an informational tool and does not guarantee exact shipping costs. Final costs are determined by USPS at the time of mailing.

// USPS typically considers packages over 108 inches in combined length and girth
// as oversized for certain services. Media Mail's surcharge logic can be nuanced.
// This is a simplified check and may not perfectly reflect all USPS scenarios.
// For this calculator, we will add a flat fee if it exceeds the common threshold.
var standardMaxCombined = 108; // inches
var oversizedThreshold = 130; // inches – USPS has different thresholds for different zones/services
var oversizedSurcharge = 5.00; // Example surcharge amount
if (combinedLengthGirth > standardMaxCombined) {
// For simplicity, we'll add a general oversized fee if it exceeds 108 inches.
// A more complex calculator would consider zone and exact thresholds.
// Let's just note it for now.
// calculatedCost += oversizedSurcharge; // Uncomment to add a surcharge
console.log("Package might be considered oversized. Combined length + girth: " + combinedLengthGirth.toFixed(1) + " inches. USPS may apply additional fees.");
// For this demo, we won't add a fee but will provide an informational message if needed.
